#21869 [NEW]: Link and Mailto parsing functions

From: spoon@nexdot.net Operating system: XP Pro PHP version: 5CVS-2003-01-24 (dev) PHP Bug Type: Feature/Change Request Bug description: Link and Mailto parsing functions First, this task can be accomplished with a regex, but it is only _so_ effective. If there was some way to make functions that would take in a string, and return a string that has all links, and all email addresses (2 seperate functions, or one with a set of switches) properly formatted to work as links. The reason it is hard with regex, is becuase it is impossible to search for a link when it can be formatted so many ways. /********** simple **************/ $string = "Hey, check out http://www.spoonified.com, and email me at spoon@nexdot.net"; $linkified = hrefparse($string); echo $linkified; /*******************************/ returns this: Hey, check out <a href="http://www.spoonified.com">http://www.spoonified.com</a>, and email me at <a href="mailto:spoon@nexdot.net">spoon@nexdot.net</a> of course, the link, the main reason regex is bad, could have many things in it, it could point to a file, have a query string in it, have no www, have many PERIODS (multiple subdomains), be https://, and also not be seperated from other text (such as "OMFGwww.spoonified.comRULES"), and the list goes on. Email addresses follow the same conditions i mentioned above (minus a few of course, and plus a few also). Maybe im just overlooking a complex enough regex to do this. I DO know it can be done. Many IRC/Instant Message programs do a wonderful job of it. They take a link, no matter what conditions, or an email address, and will show an active link once sent. Obviously there is a rexeg im too lame to understand, or a better way to accomplish it. (also, you 5.0.xCVS is still having an error on the php4apache2.dll compile, just a sidenote, no comments needed, i think you guys are already aware) -- Edit bug report at http://bugs.php.net/?id=21869&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=21869&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=21869&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=21869&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=21869&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=21869&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=21869&r=support Expected behavior: http://bugs.php.net/fix.php?id=21869&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=21869&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=21869&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=21869&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=21869&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=21869&r=dst IIS Stability: http://bugs.php.net/fix.php?id=21869&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=21869&r=gnused
