Finding all links in a text. Parsing.

Regular expression find all links in text using php. It came in handy when I needed to select images from the standard content builder plugin and create a slider.

The standard plugin added a lot of extra html code and with the help of this regular expression it was possible to clean up all the extra and completely unnecessary code.

preg_match_all('#\b(https?://[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/)))#ism', $text, $urls); 
$urls = $urls[1]; 
$urls = array_unique($urls);
print_r($urls);

preg_match_all('#\b(https?://[^\s()<>]+(?:$[\w\d]+$|([^[:punct:]\s]|/)))#ism', $text, $urls);

$urls = $urls[1];

$urls = array_unique($urls);

print_r($urls);
