Binding params for PDO statement inside a loop

Question

I\'m trying to bind parametres for SQL query inside a loop:

$db = new PDO(\'mysql:dbname=test;host=localhost\', \'test\', \'\');  
$stmt = $db->prepare(         


        

Answer 1

The problem is that bindParam requires a reference. It binds the variable to the statement, not the value. Since the variable in a foreach loop is unset at the end of each iteration, you can't use the code in the question.

You can do the following, using a reference in the foreach:

foreach ($reindex as $key => &$value) {  //pass $value as a reference to the array item
    $stmt->bindParam($key, $value);  // bind the variable to the statement
}

Or you could do this, using bindValue:

foreach ($reindex as $key => $value) {
    $stmt->bindValue($key, $value);  // bind the value to the statement
}
