 Doctrine supports dynamic binding of parameters to your query, similar to preparing queries. You can use both strings and numbers as placeholders, although both have a slightly different syntax. Additionally, you must make your choice: Mixing both styles is not allowed. Binding parameters can simply be achieved as follows:

+    [php]
     // $qb instanceof QueryBuilder
     
     // example6: how to define: "SELECT u FROM User u WHERE u.id = ? ORDER BY u.name ASC" using QueryBuilder string support

 You are not forced to enumerate your placeholders as the alternative syntax is available:

 Note that numeric placeholders start with a ? followed by a number while the named placeholders start with a : followed by a string.
 
 If you've got several parameters to bind to your query, you can also use setParameters() instead of setParameter() with the following syntax:
 
     [php]
-	// $qb instanceof QueryBuilder
+    // $qb instanceof QueryBuilder
     
     // Query here...
-	$qb->setParameters(array(1 => 'value for ?1', 2 => 'value for ?2'));
+    $qb->setParameters(array(1 => 'value for ?1', 2 => 'value for ?2'));
 
 
 Getting already bound parameters is easy - simply use the abovementioned syntax with "getParameter()" or "getParameters()":
 
     [php]
-	// $qb instanceof QueryBuilder
+    // $qb instanceof QueryBuilder
     
     // See example above
-	$params = qb->getParameters(array(1, 2));
-	// Equivalent to
-	$param  = array($qb->getParameter(1), $qb->getParameter(2));
+    $params = qb->getParameters(array(1, 2));
+    // Equivalent to
+    $param  = array($qb->getParameter(1), $qb->getParameter(2));
 
 Note: If you try to get a parameter that was not bound yet, getParameter() simply returns NULL.
