I am developing a crawler. It has worked fine throughout testing until this
morning, when suddenly it started yielding an access violation error. I have
not been able to find any explanation of this. I've reduced the script to
the following test code:





==============================














$sURL = $_GET['URL'];



echo('

Getting ' . $sURL . '

');

$sFileCont = file_get_contents('http://' . $sURL);

echo('
Dump:' . $sFileCont);



?>





==============================





Running this with various inputs, I get:



==============================

www.ennex.com/util/php/test.php?URL=www.Google.com



Getting www.Google.com



PHP has encountered an Access Violation at 0A0591E4

==============================

www.ennex.com/util/php/test.php?URL=www.BadURL.com



Getting www.BadURL.com



Warning: file_get_contents() [function.file-get-contents]:
php_network_getaddresses: getaddrinfo failed: No such host is known. in
D:\WWWRoot\ennex.com\www\util\php\test.php on line 11



PHP has encountered an Access Violation at 0A11B8D6

==============================



The second result shows that it doesn't have to successfully open a stream
to yield the error.



The "file_get_contents()" function was working just fine throughout
development of the script. Now it yields an access violation. Anybody have
any idea what is going on?



Thanks for your help.

Is allow_url_fopen enabled?

http://us.php.net/manual/en/filesystem.configuration.php#ini .allow-url-fopen

Not sure. Review above suggestion.

This should:

When I do this...
# host www.badurl.com

I get this...
Host www.badurl.com not found: 3(NXDOMAIN)

Have you move servers at all, or has the server you're running the
script on now been updated recently?
