Note Submitter: admin at nyancode dot me ---- preg_match is good but it's slower than strpos in case that you just need to check if a string occurs. So instead of using regular expression you can simply use: <?php if(strpos('This is a text', 'a') !== FALSE){ echo 'String found'; }else{ echo 'String not found'; } ?> You can use regular expression in complex case and for that a live regex testing tool is needed. Liveregex.com is one of good tools out there which help you to test and demonstrate PHP regex, you can create a permalink to share your regex too. Here's an example http://liveregex.com/0gvKo
