Question

I’m using Simple HTML Dom. I’m trying to run the following: (with WAMP)

$doc = file_get_html('http://www.scoop.it/t/curate-your-personal-learning-environment?page=3');
$comments = array();
$CommentList = $doc->find('#commentList div[class=commentContainer]');
if (count($CommentList) > 0)
    var_dump($CommentList);
foreach ($CommentList as $comment)
{
    $text = $comment->find('span[class^=author]');
    $comments[] = $this::ctrim($text[0]->innertext);
}

If I comment out the foreach loop, it runs fine.
Otherwise, the apache crashes.

One important note: If I comment out the inside of the foreach loop, it still crashes.
I added the var dump to make sure that the array has valid items.

EDIT:

Apache logs:

Answer 1

this might be a memory leak:
since your apache says:

child process exited with status 255

see here:
PHP Out of Memory – Crashes Apache?

Due to php5 circular references memory leak, after creating DOM
object, you must call $dom->clear() to free memory if call
file_get_dom() more then once.
