preg replace for links

hello there,
I have a little function for links to replace them from a string and its working fine..
I would like to add something so that if there is an image inside the link to ignore the replace
for example this code does this

$post = preg_replace('/\[url="?([^\]"]+)[\]"].*/i', '$1', $post);
 
[URL="http://google1.com"]google is a search engine[/URL]
[URL=http://google2.com]google is a search engine[/URL]
[URL=http://googleimg.com][IMG]http://google.com/logo.jpg[/IMG][/URL]
 
into
 
http://google1.com
http://google2.com
http://googleimg.com
 
 
im trying to do something so if there is [img] tags inside the [url] to NOT do a replace...
how can I do that?

Is $post a text where there can be any number of links ?

If not, if each $post only consists in one link, you can do this:

<?php
 
$posts = array(
    '[URL="http://google1.com"]google is a search engine[/URL]',
    '[URL=http://google2.com]google is a search engine[/URL]',
    '[URL=http://googleimg.com][IMG]http://google.com/logo.jpg[/IMG][/URL]');
 
foreach ($posts as $post) {
    
    if (false === stripos($post, '[img]')) {
        $post = preg_replace('/\[url="?([^\]"]+)[\]"].*/i', '$1', $post);
    }
    
    echo "$post<br>\n";
}
 
?>
