note 57640 added to function.file

I have easyPHP on my computer, which is behind a firewall(the one of my students network). I tried to execute the following script : <? $handle = file_get_contents("http://www.progonline.com/"); ?> When executed, the script returns the following error: Warning: file_get_contents(http://www.progonline.com/): failed to open stream: Bad file descriptor in c:\program files\easyphp1-8\www\test.php on line 2 I do not understand this warning, since the adress is absolutely valid (it works when introduced in any internet browser). Can anyone help? Thank you. ---- Manual Page -- http://www.php.net/manual/en/function.file.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57640 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57640&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57640&report=yes Search -- http://master.php.net/manage/user-notes.php
