Question

I’am new to PHP, so please be nice 🙂

Sometimes file_get_contents does its job and sometimes not. I have build a simple check for URLs, if they exist, on webpages. But the problem is, that even the URL exist for sure (manually checked the sourcecode), file_get_contents and preg_match do not find it. I can’t figure out why. Here’s the code:

$page = $URL_that_should_be_checked;
$checkurl = str_replace("/", "\/", $checkurl);
$page = file_get_contents($userpage);
$checkurl = "/".$checkurl."/";
$report = preg_match($checkurl, $page);

Thank you very much!!

Try this:

$page = file_get_contents($userpage);

$report = preg_match('/' . preg_quote($checkurl) . '/', $page);
