How do I remove trailing whitespace?
The function of choice here would be chop, like so:
<?php
$contents = " I'm spaced out ";
echo "<$contents>\n";
echo "<" . chop($contents) . ">";
< I'm spaced out >
< I'm spaced out>
?>
Note that the trailing space has all been removed from the second line, and also that the leading space is still there... if you want to get rid of that, it's a job for trim!
