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,
$str = '123,333,234,'; echo rtrim($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) ?>
