Lets say that $content is the content of a textarea
/*Convert the http/https to link */
$content = preg_replace('!((https://|http://)+[a-z0-9_./?=&-]+)!i', '<a target="_blank" href="$1">$1</a> ', nl2br($_POST['helpcontent'])." ");
/*Convert the www. to link prepending http://*/
$content = preg_replace('!((www\.)+[a-z0-9_./?=&-]+)!i', '<a target="_blank" href="http://$1">$1</a> ', $content." ");
This was working ok for links, but realised that it was breaking the markup when an image is within the text...
I am trying like this now:
$content = preg_replace('!\s((https?://|http://)+[a-z0-9_./?=&-]+)!i', ' <a href="$1">$1</a> ', nl2br($_POST['content'])." ");
$content = preg_replace('!((www\.)+[a-z0-9_./?=&-]+)!i', '<a target="_blank" href="http://$1">$1</a> ', $content." ");
As is the images are respected, but the problem is that url's with http:// or https:// format won't be converted now..:
google.com -> Not converted (as expected)
www.google.com -> Well Converted
http://google.com -> Not converted (unexpected)
https://google.com -> Not converted (unexpected)
What am I missing?
-EDIT-
Current almost working solution:
$content = preg_replace('!(\s|^)((https?://)+[a-z0-9_./?=&-]+)!i', ' <a href="$2" target="_blank">$2</a> ', nl2br($_POST['content'])." ");
$content = preg_replace('!(\s|^)((www\.)+[a-z0-9_./?=&-]+)!i', '<a target="_blank" href="http://$2" target="_blank">$2</a> ', $content." ");
The thing here is that if this is the input:
www.funcook.com http://www.funcook.com https://www.funcook.com funcook.com http://funcook.com https://funcook.com
All the urls I want (all, except name.domain) are converted as expected, but this is the output
www.funcook.com http://www.funcook.com https://www.funcook.com ; funcook.com http://funcook.com https://funcook.com
Note an ; is inserted, any idea why?
