note 57737 added to function.preg-replace

Here's a quick preg_replace function. It will scan an html or plain text string stored in a variable and change all web urls to html hyperlinks. These will popup in a new window. The ' target="popup" ' can easily be removed to make links appear in the current window. Useful when building forums and pulling messages or posts from a database or text file. Can also be used with <? ob_start(); ?> and <? $html = ob_get_clean(); ?> to process output buffer. For example any text matching: www.safirex.co.uk or http://www.safirex.co.uk etc. will be replaced with: <a href="http://www.safirex.co.uk" target="popup">www.safirex.co.uk</a> ----------------------------------------------------------- <? function linkScan($string) { $pattern = "/(http:\/\/)?www([\w\d\.\-]+)(\/[\w\d\.\-_]*)?/i"; $replace = "<a href=\\"http://www$2$3\\" target\\"popup\\">$0</a>"; return( preg_replace($pattern,$replace,$string) ); } ?> ----------------------------------------------------------- ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57737 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57737&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57737&report=yes Search -- http://master.php.net/manage/user-notes.php
