Er, when you call execute(), not query().

Not a bug.
bindParam() works the value by-reference, which means you passed it a reference to the $value
variable. Not
its value at the time you called it. When the loop ends and you call query(), $value will be
whatever the
last one in the $array was: 1.
Use a reference to the item in the array:
$stmt2->bindParam($param, $array[$param]);

Description:
------------
I have noticed an issue when working with MySQL and PDO prepare statements. If running a foreach on
an array which contains the params for the prepare statement, all params equal the value of the last
param in the array.
See below.
Test script:
---------------
$pdo = new PDO('mysql:dbname=netsec_v2;host=localhost;', 'root', '');
$stmt = $pdo->prepare("CREATE TABLE BugTest
(
ID int NOT NULL AUTO_INCREMENT,
PRIMARY KEY(ID),
ColumnA varchar(15) NOT NULL,
ColumnB int NOT NULL
)");
$stmt->execute();
$array = array(":ColumnA" => "A", ":ColumnB" => 1);
$stmt2 = $pdo->prepare("INSERT INTO BugTest (ColumnA,ColumnB) VALUES (:ColumnA,
:ColumnB)");
foreach($array as $param => $value){
$stmt2->bindParam($param, $value);
}
$stmt2->execute();
$res = $pdo->query("SELECT * FROM BugTest")->fetchAll(PDO::FETCH_ASSOC);
var_dump($res);
Expected result:
----------------
ColumnA = A
ColumnB = 1
Actual result:
--------------
ColumnA = 1
ColumnB = 1
