php script that print all src of any image in a splider site

I'm using SimpleHTMLDOM to retrive all uri of all images of a site, but during the execution i'm g开发者_运维技巧etting a memory usage error, how to solve?

$count = 0;
$last = 1721;
include('simple_html_dom.php');

while ( $count <= $last) { 

$html = file_get_html('http://myuri/?from='.$count);

// find all image inside post div
    foreach($html->find('div.itemPost img') as $e) {

        echo $e->src . '<br>';

    }

}

this is the error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 35 bytes) in /home/peppo1616/public_html/script/simple_html_dom.php on line 1189

Call the destructor after looping through img tags and assign null to $html to clear some memory.

while ( $count <= $last) { 
    $html = file_get_html('http://myuri/?from='.$count);

    // find all image inside post div
    foreach($html->find('div.itemPost img') as $e) {
        echo $e->src . '<br>';
    }

    $html->clear();
    $html = null;
}

On a side note, I don't see any incrementation of $count, you may end with infinite loop.
