How do I filter php code in $_POST?

Do you mean all values? Then:

[pre]
array_walk( $_POST, function( &$value, $key ){
$value = filter_function( $value ); // The filter function can be intval, floatval, or anything.. even a custom function will do.
});
[/pre]

Things to look into after considering the above code:
