Bug #16642 Updated: replace url with a link

ID: 16642 Updated by: andreas.schempp@gmx.ch Reported By: andreas.schempp@gmx.ch Status: Closed Bug Type: Feature/Change Request Operating System: Linux 2.4.17 (self compiled) PHP Version: 4.1.2 New Comment: Its not as simple as you think, specialy for non-preg-users. I could not find any real documentation wich arguments could be used for preg_replace, only the ones at ereg_replace, posted from a user. I needed half a week to construct the things you see here...

I find your argument lacking. Cheers, Rob. ------------------------------------------------------------------------ [2002-04-16 13:31:23] sander@php.net No, we can't include a function for stuff like this. This can be easily done in PHP, so there's no need for a native function. ------------------------------------------------------------------------ [2002-04-16 13:27:07] andreas.schempp@gmx.ch I could not find any function to replace an url within a string with a link if someone writes http://www.php.net, I want I to be replaced with <a href="http://www.php.net> I saw this on your page too, its easy to recreate your function myself with $string = preg_replace("((http://)([a-zA-Z1-9\-_\.]+\.[a-zA-Z1-9\-_]+\.[a-z]{2,3}(/[a-z\-/\._\?=&]+)?))", "<a href=\"\\1\\2\" target=\"_blank\">\\0</a>", $string); but wouldnt it be nice to replace an url like www.php.net too? For now, I use $string = preg_replace("((http://|ftp://)?([a-zA-Z1-9\-_\.]+\.[a-zA-Z1-9\-_]+\.[a-z]{2,3}(/[a-z\-/\._\?=&]+)?))", "<a href=\"\\1\\2\" target=\"_blank\">\\0</a>", $string); to convert every url to an link. but if you have an url like www.php.net, it will create a link like <a href="www.php.net">, wich will not work. To prevent this, I use $string = preg_replace("((href=\")([a-zA-Z1-9\-_\.]+\.[a-zA-Z1-9\-_]+\.[a-z]{2,3}(/[a-z\-/\._\?=&]+)?))", "href=\"http://\\2", $string); wich will replace anything like href="something.php.net with href="http://something.php.net I think it will be nice for other people to include (something like) this function in php, because many people would use it thanks ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16642&edit=1
