corrupshun Posted January 4, 2010 Share Posted January 4, 2010 I do not understand it. Whenever something is going to be replaced it looks like complete crap... Can someone explain what this means and explain how you deciphered it? <?php preg_replace("/(<\/?)(\w+)([^>]*>)/e", "'\\1'.strtoupper('\\2').'\\3'", $html_body); ?> That is some random code I found on a tutorial for this.. I cannot read it.. Thanks! Link to comment https://forums.phpfreaks.com/topic/187179-preg_replace/ Share on other sites More sharing options...

MadTechie Posted January 4, 2010 Share Posted January 4, 2010 The RegEx converts the html tags to upper case. for example <?php $html_body = "<body><P>Hello World</P></body>"; $html_body = preg_replace("/(<\/?)(\w+)([^>]*>)/e", "'\\1'.strtoupper('\\2').'\\3'", $html_body); echo $html_body; ?> returns <BODY><P>Hello World</P></BODY> note that body becomes BODY Link to comment https://forums.phpfreaks.com/topic/187179-preg_replace/#findComment-988460 Share on other sites More sharing options...
