This is a little late... but I'm old and slow.......
Regarding Extending PDOStatement and PDO I found that sending the PDOExtended class by reference helps:
    In the constructor after parent::__construct() :
$this->setAttribute(\PDO::ATTR_STATEMENT_CLASS,array('PDOStatementExtended', [&$this]));}

And in
class PDOStatementExtended extends \PDOStatement
{
 
  protected function __construct
  (
    \PDO &$PDO,
   )

When using prepared statements there is no official PDO feature to show you the final query string that is submitted to a database complete with the parameters you passed.

Use this simple function for debugging. The values you are passing may not be what you expect.

<?php
//Sample query string
$query = "UPDATE users SET name = :user_name WHERE id = :user_id";

//Sample parameters
$params = [':user_name' => 'foobear', ':user_id' => 1001];

function
build_pdo_query($string, $array) {
   
//Get the key lengths for each of the array elements.
   
$keys = array_map('strlen', array_keys($array));

   
//Sort the array by string length so the longest strings are replaced first.
   
array_multisort($keys, SORT_DESC, $array);

    foreach(
$array as $k => $v) {
       
//Quote non-numeric values.
       
$replacement = is_numeric($v) ? $v : "'{$v}'";

       
//Replace the needle.
       
$string = str_replace($k, $replacement, $string);
    }

    return
$string;
}

echo
build_pdo_query($query, $params);    //UPDATE users SET name = 'foobear' WHERE id = 1001
?>

Merge the prepare() and execute() in one function like a sprintf().
And like sprintf, I choose to use unnamed args (?) ;)

you could still use old insecure query() ( not prepared ) with renamed function :)

<?php
class MyPDO extends PDO{

    const
PARAM_host='localhost';
    const
PARAM_port='3306';
    const
PARAM_db_name='test';
    const
PARAM_user='root';
    const
PARAM_db_pass='';

    public function
__construct($options=null){
       
parent::__construct('mysql:host='.MyPDO::PARAM_host.';port='.MyPDO::PARAM_port.';dbname='.MyPDO::PARAM_db_name,
MyPDO::PARAM_user,
MyPDO::PARAM_db_pass,$options);
    }

    public function
query($query){ //secured query with prepare and execute
       
$args = func_get_args();
       
array_shift($args); //first element is not an argument but the query itself, should removed

       
$reponse = parent::prepare($query);
       
$reponse->execute($args);
        return
$reponse;

    }

    public function
insecureQuery($query){ //you can use the old query at your risk ;) and should use secure quote() function with it
       
return parent::query($query);
    }

}

$db = new MyPDO();
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_OBJ);

$t1 = isset($_GET["t1"])?$_GET["t1"]:1; // need to be securised for injonction
$t2 = isset($_GET["t2"])?$_GET["t2"]:2; // need to be securised for injonction
$t3 = isset($_GET["t3"])?$_GET["t3"]:3; // need to be securised for injonction

$ret = $db->query("SELECT * FROM table_test WHERE t1=? AND t2=? AND t3=?",$t1,$t2,$t3);
//$ret = $db->insecureQuery("SELECT * FROM table_test WHERE t1=".$db->quote($t1));

while ($o = $ret->fetch())
{
    echo
$o->nom.PHP_EOL;
}

You may also have to edit /etc/freetds.conf. Make sure the TDS version is recent, e.g., "tds version = 8.0".

This works to get UTF8 data from MSSQL:

<?php
$db
= new PDO('dblib:host=your_hostname;dbname=your_db;CHARSET=gb2312', $user, $pass);
?>

I ran into a real annoying bug/feature when using PDO for SQL statements that use SQL user variables.  I was working on some logic for a Geo Proximity Search for an events-venues system (sharing is caring so it's below) and it just wouldn't take and the errors returned were garbage. The SQL was sound as I verified it.  So if you're having this issue, I hope this helps.  What you need to do is break apart the query into two...

From:
<?php
$sql
="set @latitude=:lat;
set @longitude=:lon;
set @radius=20;

set @lng_min = @longitude - @radius/abs(cos(radians(@latitude))*69);
set @lng_max = @longitude + @radius/abs(cos(radians(@latitude))*69);
set @lat_min = @latitude - (@radius/69);
set @lat_max = @latitude + (@radius/69);

SELECT *,
3956 * 2 * ASIN(SQRT(POWER(SIN((@latitude - ABS(venue_lat)) * PI()/180 / 2),2) + COS(@latitude * PI()/180) * COS(ABS(venue_lat) * PI()/180) * POWER(SIN((@longitude - venue_lon) * PI()/180 / 2),2))) AS distance
FROM events LEFT JOIN venues ON venues.venue_id = events.venue_fk
WHERE (venue_lon BETWEEN @lng_min AND @lng_max)
AND (venue_lat BETWEEN @lat_min and @lat_max)
AND events.event_date >= CURDATE()
AND events.event_time >= CURTIME()
ORDER BY distance DESC;"
;

$stmt = $this->_db->prepare($sql);
$stmt->bindParam(':lat', $lat, PDO::PARAM_STR);
$stmt->bindParam(':lon', $lon, PDO::PARAM_STR);
$stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
$stmt->bindParam(':max', $max, PDO::PARAM_INT);
$stmt->execute();
?>

To:
<?php
$sql
= "SET @latitude=:lat;
SET @longitude=:lon;
SET @radius=20;
SET @lng_min=@longitude - @radius/abs(cos(radians(@latitude))*69);
SET @lng_max=@longitude + @radius/abs(cos(radians(@latitude))*69);
SET @lat_min=@latitude - (@radius/69);
SET @lat_max=@latitude + (@radius/69);"
;

$this->_db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
$stmt = $this->_db->prepare($sql);
$stmt->bindParam(':lat', $lat, PDO::PARAM_STR);
$stmt->bindParam(':lon', $lon, PDO::PARAM_STR);
$stmt->execute();

$sql = "SELECT *,
(3956 * 2 * ASIN(SQRT(POWER(SIN((@latitude - ABS(venue_lat)) * PI()/180 / 2),2) + COS(@latitude * PI()/180) * COS(ABS(venue_lat) * PI()/180) * POWER(SIN((@longitude - venue_lon) * PI()/180 / 2),2)))) AS distance
FROM events LEFT JOIN venues ON venues.venue_id = events.venue_fk
WHERE (venue_lon BETWEEN @lng_min AND @lng_max)
AND (venue_lat BETWEEN @lat_min and @lat_max)
AND events.event_date >= CURDATE()
AND events.event_time >= CURTIME()
ORDER BY distance DESC
LIMIT :offset,:max;"
;
              
$stmt = $this->_db->prepare($sql);
$stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
$stmt->bindParam(':max', $max, PDO::PARAM_INT);
$stmt->execute();
?>

Hope this helps anyone out there!

I decided to create a singleton wrapper for PDO that ensures only one instance is ever used.
It uses PHP 5.3.0's __callStatic functionality to pass on statically called methods to PDO.

This means you can just call it statically from anywhere without having to initiate or define the object.

Usage examples:

<?php
DB
::exec("DELETE FROM Blah");

foreach(
DB::query("SELECT * FROM Blah") as $row){
       
print_r($row);
}
?>

Code:

<?php

class DB {
   
    private static
$objInstance;
   
   
/*
     * Class Constructor - Create a new database connection if one doesn't exist
     * Set to private so no-one can create a new instance via ' = new DB();'
     */
   
private function __construct() {}
   
   
/*
     * Like the constructor, we make __clone private so nobody can clone the instance
     */
   
private function __clone() {}
   
   
/*
     * Returns DB instance or create initial connection
     * @param
     * @return $objInstance;
     */
   
public static function getInstance(  ) {
           
        if(!
self::$objInstance){
           
self::$objInstance = new PDO(DB_DSN, DB_USER, DB_PASS);
           
self::$objInstance->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        }
       
        return
self::$objInstance;
   
    }
# end method
   
    /*
     * Passes on any static calls to this class onto the singleton PDO instance
     * @param $chrMethod, $arrArguments
     * @return $mix
     */
   
final public static function __callStatic( $chrMethod, $arrArguments ) {
           
       
$objInstance = self::getInstance();
       
        return
call_user_func_array(array($objInstance, $chrMethod), $arrArguments);
       
    }
# end method
   
}
?>

Be careful with PDO extends : if you use the smileaf's example, PDO will close the connection only at the end of the script, because of the "array( $this )" parameter used with the setAttribute() method.

Instead, I use only this :
    $this->setAttribute( PDO::ATTR_STATEMENT_CLASS, array( $this->statementClassName, array() ) );

And in prepare() and query() method you can populate the "dbh" if you really need it.

If you will make a OBJ row from PDO you can use this eg.

$resKampange = $dbc->prepare( "SELECT * FROM Table LIMIT 1" );
$resKampange->execute();
$rowKampange = $resKampange->fetch( PDO::FETCH_OB );

echo $rowKampange->felt1;

Good lock :0)
nospam dot list at unclassified dot de 13-Nov-2007 04:24
When using persistent connections, pay attention not to leave the database connection in some kind of locked state. This can happen when you start a transaction by hand (i.e. not through the PDO->beginTransaction() method), possibly even acquire some locks (e.g. with "SELECT ... FOR UPDATE", "LOCK TABLES ..." or in SQLite with "BEGIN EXCLUSIVE TRANSACTION") and then your PHP script ends with a fatal error, unhandled exception or under other circumstances that lead to an unclean exit.

To use that database again, it may then be necessary to disable the persistence attribute to get a new database connection or restart the web server. (Persistent connections should not work with a PHP-CGI anyway.) It does not work (tested with PHP 5.2.3/WinXP and SQLite) to close a persistent database connection - it will not actually be closed but instead returned to PDO's connection pool.

The only thing you can do to resolve the lock as a regular user (I imagine) is to try and get all of your persistent connections in a single script and unlock the tables resp. end the transactions with the appropriate SQL statements ("UNLOCK TABLES" in MySQL, "ROLLBACK" for transactions). Should they fail, there is no problem, but one or some of them might succeed and thereby resolve your locking problem.

Example 5:
<?php
try {
 
$dbh = new PDO('odbc:SAMPLE', 'db2inst1', 'ibmdb2',
      array(
PDO::ATTR_PERSISTENT => true));
.......
} catch (
Exception $e) {
 
$dbh->rollBack();
  echo
"Failed: " . $e->getMessage();
}
?>

We must change the last two lines to catch the error connecting to the database:

} catch (Exception $e) {
  echo "Failed: " . $e->getMessage();
  $dbh->rollBack();
}
?>

Not all PDO drivers return a LOB as a file stream; mysql 5 is one example. Therefore when streaming a mime typed object from the database you cannot use fpassthru.

The following is a modified example that works with a mysql database. (Tested FreeBSD v 6.2 with mysql 5.0.45 and php 5.2.3)

<?php
ob_start
();
$db = new PDO('mysql:host=localhost;dbname=<SOMEDB>', '<USERNAME>', 'PASSWORD');
$stmt = $db->prepare("select contenttype, imagedata from images where id=?");
$stmt->execute(array($_GET['id']));
$stmt->bindColumn(1, $type, PDO::PARAM_STR, 256);
$stmt->bindColumn(2, $lob, PDO::PARAM_LOB);
$stmt->fetch(PDO::FETCH_BOUND);
ob_clean();
header("Content-Type: $type");
echo
$lob; // fpassthru reports an error that $lob is not a stream so echo is used in place.
ob_end_flush();
?>

Please note the inclusion of buffer control. I only needed this when using 'include','include_once','require', or 'require_once' - my feeling is there is a subtle issue with those options as even an empty include file caused a buffer issue for me. === AND YES, I DID CHECK MY INCLUDE FILES DID NOT HAVE SPURIOUS WHITESPACE ETC OUTSIDE THE <?php ?> DELIMITERS! ===

It seems MySQL doesn't support scrollable cursors. So unfortunately PDO::CURSOR_SCROLL wont work.
djlopez at gmx dot de 12-Mar-2007 05:04
Note this:

Won't work:
$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit WHERE ? < ?');

THIS WORKS!
$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit WHERE calories < ?');

Parameters cannot be applied on column names!!

If you intend on extending PDOStatement and your using
setAttribute(PDO::ATTR_STATEMENT_CLASS, ...)
you must override the __construct() of your PDOStatement class.
failure to do so will result in an error on any PDO::query() call.
Warning: PDO::query() [function.PDO-query]: SQLSTATE[HY000]: General error: user-supplied statement does not accept constructor arguments

Here is a minimum PDO and PDOStatement class
<?php
class Database extends PDO {
    function
__construct($dsn, $username="", $password="", $driver_options=array()) {
       
parent::__construct($dsn,$username,$password, $driver_options);
       
$this->setAttribute(PDO::ATTR_STATEMENT_CLASS, array('DBStatement', array($this)));
    }
}
class
DBStatement extends PDOStatement {
    public
$dbh;
    protected function
__construct($dbh) {
       
$this->dbh = $dbh;

If you use $dbh = new PDO('pgsql:host=localhost;dbname=test_basic01', $user, $pass); and you get the following error:
PHP Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE[08006] [7] could not connect to server: Connection refused\n\tIs the server running on host "localhost" and accepting\n\tTCP/IP connections on port 5432?'
then as pointed out under pg_connect at: http://www.php.net/manual/en/function.pg-connect.php#38291
******
you should try to leave the host= and port= parts out of the connection string. This sounds strange, but this is an "option" of Postgre. If you have not activated the TCP/IP port in postgresql.conf then postgresql doesn't accept any incoming requests from an TCP/IP port. If you use host= in your connection string you are going to connect to Postgre via TCP/IP, so that's not going to work. If you leave the host= part out of your connection string you connect to Postgre via the Unix domain sockets, which is faster and more secure, but you can't connect with the database via any other PC as the localhost.
******
Sincerely,
Aouie

If you need to get Output variable from MSSQL stored procedure, try this :

-- PROCEDURE
CREATE PROCEDURE spReturn_Int @err int OUTPUT
AS
SET @err = 11
GO

$sth = $dbh->prepare("EXECUTE spReturn_Int ?");
$sth->bindParam(1, $return_value, PDO::PARAM_INT|PDO::PARAM_INPUT_OUTPUT);
$sth->execute();
print "procedure returned $return_value\n";

I use PDO with the ODBC driver to query stored procedures in a MS SQL Server 2005 Database under Windows XP Professional with IIS 5 and PHP 5.1.4. You may have the same problems with a different configuration.

I experienced 2 very time consuming errors:

1. The first one is when you return the result of a SELECT query, and you get the following clueless message:
>>> Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[24000]: Invalid cursor state: 0 [Microsoft][SQL Native Client]Invalid cursor state (SQLFetchScroll[0] at ext\pdo_odbc\odbc_stmt.c:372)' in (YOUR_TRACE_HERE) <<<
Your exact message may be different, the part to pay attention to is "Invalid cursor state".

-> I found that I had this error because I didn't include "SET NOCOUNT ON" in the *body* of the stored procedure. By default the server returns a special piece of information along with the results, indicating how many rows were affected by the stored procedure, and that's not handled by PDO.

2. The second error I had was:
>>> Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22003]: Numeric value out of range: 0 [Microsoft][SQL Native Client]Numeric value out of range (SQLFetchScroll[0] at ext\pdo_odbc\odbc_stmt.c:372)' in (YOUR_TRACE_HERE) <<<
Another meaningless error "Numeric value out of range"...

-> I was actually returning a date datatype (datetime or smalldatetime) "as is", that is, without converting it to varchar before including it in the result set... I don't know if PDO is responsible for converting it to a PHP datatype, but it doesn't. Convert it before it reaches PHP.

I wanted to extend PDO class to store statistics of DB usage, and I faced some problems. I wanted to count number of created statements and number of their executings. So PDOStatement should have link to PDO that created it and stores the statistical info. The problem was that I didn't knew how PDO creates PDOStatement (constructor parameters and so on), so I have created these two classes:

?>

Classes have properties with original PDO and PDOStatement objects, which are providing the functionality to PDOp and PDOpStatement.
From outside, PDOp and PDOpStatement look like PDO and PDOStatement, but also are providing wanted info.

Below is an example of extending PDO & PDOStatement classes:

<?php

If your having problems re-compiling PHP with PDO as shared module try this.

--enable-pdo=shared
--with-pdo-mysql=shared,/usr/local/mysql
--with-sqlite=shared
--with-pdo-sqlite=shared

1. If PDO is built as a shared modules, all PDO drivers must also be
built as shared modules.
2. If ext/pdo_sqlite is built as a shared module, ext/sqlite must also
be built as a shared module.
3. In the extensions entries, if ext/pdo_sqlite is built as a shared
module, php.ini must specify pdo_sqlite first, followed by sqlite.

Watch out for putting spaces in the DSN
mysql:host=localhost;dbname=test works
mysql: host = localhost; dbname=test works
mysql: host = localhost; dbname = test doesn't work...
