[RESOLVED] preg_match_all question

[swissmissflash]

Hello,

I was hoping someone could help me with this... I did search before asking and found part of my answer. 😃

What I am trying to do is use preg_match_all() to find and return the links inside an image tag.

What I got to do that is...

~<img src=\"([^\"]*)\"[^>]*>(.*)~

which would return something like...

http://somewebsite.com/images/somepic.gif

now what I would like to do is further expand that search and only pickup the links that have a certain string in them... for example.

http://somewebsite.com/images/somepicicon.gif 

Say I wanted to find the links in image tags that contain the term icon in them.... how would I go about doing that?

Thanks for your time 🙂

foreach ($image_urls as $url)
{
  if (strpos($url, 'icon'))
  {
    $icon_urls[] = $url;
  }
}

// we now have a list of icon urls in $icon_urls;

Edit: actually you would probably also want to trim away everything up to the final / character so that you are only checking the filename for 'icon' and not the whole url. You can do that in any number of ways like using strrpos to get the position of the last / or you can explode on / and use the last element .

For example:

// add me to the look before the if (strpos($url, 'icon') line
$filename = substr($url, strrpos($url, '/'));
