I need a preg_match pattern

[mda_omega]

I have a site that have these lines involved:

...
<div class="post_icon">
	<div class="post_icon_overlay"> </div>
	<img src="http://localhost/wp/65a39792ad0fc80.jpg">
</div>
...

I have made a function that is trying to grab the img address. But I cannot make a good pattern for it.

function GetImg($pageurl){
   $contents = @file_get_contents($pageurl);
   if (!$contents) return FALSE;
   preg_match(' ??? ', $contents, $matches);
   return $matches[1];
} 

can any one help?

If that is the exact pattern and that is a tab i think this should do it..

'/.*?class="post_icon".*?\t<img src="(.*?)">/s'

'/.*?class="post_icon".*?\t<img src="(.*?)">/s' 

Works. thank you.

[mda_omega]

what about all images that has the same prefix url ?

http://localhost/2450/

I cannot change the function, may you please change it for me? these are examples

http://localhost/2450/ss_3ba0cf8efe4c69a96fe6.600x338.jpg?t=1288373899

can we see the image addresses in context? We need to see what separates one image address from another. Worded another way: what does the code look like where at least one of the image addresses is located.

bluewalrus, why can't the first pattern be simplified just a wee bit to <img src="(.*?)">?

[bluewalrus]

The first pattern was to pull the images contained in post_icon.

I think per the new requirement this should work. If not we'd need to see the actual code.

'/<img src="(http:\/\/localhost\/2450\/.*?)">/' 

[james438]

yes, but that is not what he was asking for. or at least I am not seeing that in his initial post.
Either way, I would like to see the actual code mda_omega.

[mda_omega]

you both were right I needed something between what you said. all the images that has the same address. I think I should use preg_match_all instead. Am I right?

   $contents = @file_get_contents($pageurl);
   if (!$contents) return FALSE;
   preg_match_all('/<img src="(http:\/\/localhost\/2450\/.*?)">/', $contents, $matches); 

So. the other problem is. How can I reach them one by one?

is it good?

echo $matches[0];
echo $matches[1];
echo $matches[2];
... 

I dont need to get errors, so, how can I figure out how many they are? Do I need a loop to use them one by one??

[bluewalrus]

You can use the foreach function

http://php.net/manual/en/control-structures.foreach.php

so it'd be

foreach ($matches as $value) {
    echo $value;
} 

assuming that array has all the values you want.

thank you thank you thank you :xxx

That was simple and effective.
