如何在Simple HTML DOM中使用load_file（）时忽略警告？

Question

I use SIMPLE HTML DOM. Some pages take a long time -> then Warning (HTTP request failed) -> find() doesn`t work! FATAL ERROR! How to go to the next page?

$items = [...];
foreach ($item as $link) {
    $html = new simple_html_dom();
    $html -> load_file($link);
    if (WHAT SHOULD I WRITE HERE TO START PARSING WHEN $html is OK?) {
        some parsing
    }
}

If the line $html -> load_file($link); is the one causing the page timeout, you can do nothing on the next line.

Maybe consider increasing the set_time_limit or deactivating it set_time_limit(0) before the foreachloop.

$items = [...];
set_time_limit(300);
foreach ($item as $link) {
    $html = new simple_html_dom();
    $html -> load_file($link);
    if (WHAT SHOULD I WRITE HERE TO START PARSING WHEN $html is OK?) {
        some parsing
    }
}

You should read the set_time_limit documentation and max execution time documentation.

Be aware that increasing this value in a web context may not be a great idea. Also, be aware that according to PHP documentation, apache seems to have a timeout at 300 seconds (5 minutes).
