Re: [PHP] fopen() for http:// sometimes working, sometimes not

It's not the URL because the same URL will not work one time but will work another time. What needs to be escaped for a URL anyway? I am just changing spaces to '%20' now. I will try upgrading to 5.2.5. I'm using 5.2.3 now. Thanks, Albert -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Arbitrary code can still be injected unless it's properly sanitized, but that's beyond the scope here. Mainly, make sure quotes (single and double) are being converted. -- Daniel P.
