Regular expression

[tmh766]

Hi everyone

 

I have been trying for hours to understand a way to do this.

 

I need to replace all instances of "http" all the way to the first space character (get a url), as long as it does not end in ".jpg",".gif"...etc

 

I can match a URL,

/(http[^\s]+)/i

but cannot figure out a way to not match it if a picture extension is present in the end.

 

Thank you!

can you give some examples please.

I assume

http:\\www.domain.com\blar.html < - replaced with ?

http:\\www.domain.com\blar.jpg < - NOT replaced

try this

$HTML = "test http:\\www.domain.comj\blar.html ing
http:\\www.domain.com\test\blar.jpg
http:\\www.domain.com\test\blar.html
http:\\www.domain.com\blar.html
http:\\www.domain.com\blar.gif
http:\\www.domain.com\blar.php
http:\\www.domain.com\blar.png
http:\\www.domain.com\blar.html
http:\\www.domain.com\blar.jpg";
$HTML = preg_replace('/\bhttp:\\\\\S+?\\\\[^.]*\.(jpg|png|gif)\S*\b/i', '', $HTML );
echo $HTML;
