[SOLVED] Validating images

[gerkintrigg]

Hi everyone.

 

I am trying to check whether the image links in a string containing HTML, is a relative link or an absolute one... in other words I need the full

http://www.whatever.com/

in order to make sure that the images show correctly.

 

I have managed to do this to a degree with this code:

#ensure the images are grabbed:
$src_old_content=GetBetween($page, 'src="', '"');

$pos = strpos($src_old_content, $findme);
#if it doesn't begin with http:// then make it begin with that:
if ($pos !== false) {
} else {
     $src_new_content=$url.'/'.$src_old_content;
}
$page=str_replace($src_old_content, $src_new_content, $page);

Yes I wrote a function to get what's between the start and end variables and referenced that function.

 

The only issue I have now is that it only replaces the first occurrence of the image code in the string. I want it to replace every occurrence. Can I do that with preg_replace or do I need to use some kind of loop?

 

Thanks.

Nevermind:

#ensure the images are grabbed:
$img_replace=explode('src="',$old_page);
foreach ($img_replace as $key => $value){
$img_path=explode('"',$value);
$pos = strpos($img_path[0], $findme);
#if it doesn't begin with http:// then make it begin with that:
if ($pos !== false) {
} else {
     $src_new_content=$url.'/'.$img_path[0];
}
$page=str_replace($img_path[0], $src_new_content, $page);
}
