filtering?

[codrgii]

in php how am i able to filter all the $_GET varables without doing something like

 

<?

$_GET['varable1'] = filterfunctionhere($_GET['varable1'])

$_GET['varable2'] = filterfunctionhere($_GET['varable2'])

$_GET['varable3'] = filterfunctionhere($_GET['varable3'])

$_GET['varable4'] = filterfunctionhere($_GET['varable4'])

?>

 

but do something like

 

<?

$_GET['collect_all_1234varables_here'] = filterfunctionhere($_GET['collect_all_1234varables_here'])

?>

 

how in php am i able to do that? and would someone explain what $_GET[0] would be used for?

As long as you want to run filterfunctionhere on all elements in $_GET then you can use array_map.

$getcopy = array_map("filterfunctionhere", $_GET);

Note how that isn't overwriting $_GET. Avoid doing so with important variables like $_GET and $_POST.

 

Now what's this about $_GET[0]?
