I have a patch for that. it will be added after 0.10.0.

I add a new comment.
Why input_get TRIM float and integer filter but NOT boolean filter in input ???
Exemple :
$_GET['myint'] = '  42  '; //OK
$_GET['myfloat'] = '    42.5    '; //OK
$_GET['myboolean'] = '     On '; //KO

Because I added it for integer and float values. I think it makes sense to add trim white chars for numeric values, as does PHP itself in casting operations.

A trim tag would have other meanings when used with string values.

int, float and boolean use trim now.

The trim flag will be added after 5.2.0RC3.

In most case, most people need to trim STRING inputs.

In now days, we must trim $_POST like this

<?php
function trim_value(&$value){ 
    $value = trim($value); 
}
array_walk_recursive($_POST,'trim_value');
?>

I think we can write less code and get better performance, while do this job with filter extension.

hope you can understand i means, and sorry for my poor english :)

Is this still relevant?
