ltrim behavior.

This might be old for some of you but I never encountered it until today and I would like to know why this is happening. Here's the situation: php > $a='data[options][name]'; php > echo ltrim($a,'data['); options][name] Just as I expected. Next one: php > $a='options[options][name]'; php > echo ltrim($a,'options['); ][name] UH, what? Not exactly what I expected. This works: php > $a='options[options][name]'; php > echo ltrim(ltrim($a,'options'),'['); options][name] Can somebody explain the second behavior? Is this a known bug in PHP, I'm running PHP 5.2.6 on Ubuntu. -- Peter van der Does GPG key: E77E8E98 WordPress Plugin Developer http://blog.avirtualhome.com GetDeb Package Builder/GetDeb Site Coder http://www.getdeb.net - Software you want for Ubuntu
