Trouble w/ file()

[Anon]

Hello,

I've been at this PHP thing for about 13 hours now, and I love it!

Got a newbie problem that may be PHP, may be my host:

Trying to grab a page of HTML and add line numbers to it (right out of the php.net documentation for file() ):

<?php
// get a web page into an array and print it out
$fcontents = file( 'http://www.php.net' );
while ( list( $line_num, $line ) = each( $fcontents ) ) {
echo "<b>Line $line_num:</b> " . htmlspecialchars( $line ) . "<br>\n";
}
?>

This script doesn't work for any file that is not on my server, but works fine for files within my domain.
http://www.sizzlinsummer.com/index3.php3 - works fine - target=index.htm
http://www.sizzlinsummer.com/index4.php3 - doesn't work - target=http://www.php.net

Am I doing something wrong, or is my hosting provider not allowing this to happen?

Thanks in advance,
Alan

It sounds like the PHP on your web-server has been built without fopen-wrappers support.

Thank you for the help!

I don't think my hosting provider has much experience with PHP. From what I can get from the documentation, turning off support for external files is something they would have done on purpose: Chapter 19 -
"As long as support for the "URL fopen wrapper" is enabled when you configure PHP (which it is unless you explicitly pass the
--disable-url-fopen-wrapper flag to configure), you can use HTTP and FTP URLs with most functions that take a filename as a parameter"

Would that be something they would have put into a configuration file? Can it be enabled without recompiling the code? And finally, is there a place to see if it's turned on or off?

Thanks again,
Alan
