<?php
$id = 3;
//let's wrap everything within a try/catch block
try {
$pdo = new PDO('mysql:host=localhost;dbname=myDatabase', $username, $password);
$query = $pdo->prepare('SELECT * FROM myTable WHERE id = :id');  
//set the ATTR_ERRMODE and ERRMODE_EXCEPTION to see if something goes wrong
$pdo-> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$query = $pdo->prepare('SELECT * FROM myTable WHERE id = :id');
$query->execute(array( 'id' => $id ));
while ($row = $query->fetch()) {
//you can get an object instead of an array by using:
//while($row = $stmt->fetch(PDO::FETCH_OBJ))
print_r($row); }
}
catch (PDOException $e) {
echo 'ERROR: '.$e - > getMessage();
}
?>

you can also use the bindParam method, like:

PHP

$query-&gt; bindParam(':id', $id, PDO::PARAM_INT);
$query-&gt; execute();
