Re: Serious Fopen Problems - not newbie :)

Any help debugging the below would help greatly :) ok, I ran strace and tried this via a command line: bash-2.05$ strace ./tmp.php A snippet from tmp.php looks like this: ##################################################### #!/usr/local/bin/php -q <?php $fopen = fopen("http://www.php.net/", "r"); exit; ##################################################### This was the
