First of all,
trim filters both ends of the string,
rtrim filter string tail,=chop()
ltrim filters string headers.
Filter the keys in the string with str_replace.
So for example,
PHP code
$str = '123,333,234,';
echo rtrim($str, ',');
rtrim instance code 2
<?php
$text = "\t\tThese are a few words :) ... ";
$trimmed = rtrim($text);
// $trimmed = "\t\tThese are a few words :) ..."
$trimmed = rtrim($text, " \t.");
// $trimmed = "\t\tThese are a few words :)"
$clean = rtrim($binary, "\x00..\x1F");
// trim the ASCII control characters at the end of $binary
// (from 0 to 31 inclusive)
?>
