Function similar to rtrim only this will truncate the string at the 1st occurence of any character from $charlist
<?php
function rstrip($string, $charlist = "\t ") {
// removes everything from first occurence of char in charlist to end of string
$charlist = str_split($charlist);
$pos = strlen($string);
foreach ($charlist as $char) {
$pos = min(strpos($string, $char), $pos);
}
$string_stripped = substr($string, 0, $pos);
return $string_stripped;
}
?>
