turn text into link

Question

I am trying to turn the link of an image into the image inside the tag, however I am having difficulties when there is the image, the same I try to do with the link

in case I use the code below

$reply = preg_replace('#((http://|https://|//)([^\s]*)\.jpg|gif|png|JPG))#',  
'<img src="$1" alt="" width="" height="" />', $data['reply']);

It works great when the link is posted like this

http://wallpaper.ultradownloads.com.br/276255_Papel-de-Parede-Meme-Obama-Not-Bad_1280x1024.jpg 

but if the text has something like this

<img src="http://wallpaper.ultradownloads.com.br/276255_Papel-de-Parede-Meme-Obama-Not-Bad_1280x1024.jpg" > 

he’ll try to turn too, as I might do?

Answer 1

A suggested code change.

Test like this:

preg_match('/(https?:\/\/[^\s\'\"]*)/', $data['reply'], $match);
$reply = '<img src="'.$match[0].'" alt="" width="" height="" />';

Example: http://ideone.com/qpknsU

I find this way cleaner. First extract the desired url, then concatenate into the string.

Answer 2

If I understand well what you want is to take the url only of "Anchor" tags and when you run the code it takes everything that is url.

So you just need to make this little change to the code that Sergio posted on top

preg_match('/href="(https?:\/\/[^\s\'\"]*)/', $data['reply'], $match);
$reply = '<img src="'.$match[1].'" alt="" width="" height="" />';
