string chop(string $str [, string $charlist])
(PHP 4, PHP 5)
| $str | The string to manipulate (trim whitespace) |
|---|---|
| $charlist | Optional string of characters to strip from the right side of $str |
| RETURNS | Returns the modified string with the specified characters removed |
This function is an alias for the rtrim function. It trims specific characters (specified by $charlist) from the end of the string argument. If the optional $charlist argument is not specified, all whitespace characters will be removed.
