Trim Excess Whitespace
This snippet is useful when your input is full of tons of extra unwanted whitespace. Say if you are making a chat program and someone just hammers on the spacebar just a little too much.
Snippet:
-
<?
-
// this function will trim out excess whitespace
-
// this will take something like this " h i"
-
// .. and make it into this "h i"
-

-
-
function trim_excess($str)
-
{
-
$str = trim(preg_replace('/\s+/', ' ', $str));
-
return $str;
-
}
-
?>
Example:
-
<?
-
$str = trim_excess($str);
-
?>

Found this one good for filtering input for shoutboxes or chat programs.
