[Resolved] help,help, an error has occured when I call 'fopen()'

[powerpolly]

this puzzled me for a few days£¬when I use the function 'fopen' with following :

<?php
$url = "http://www.php.net";
$handle = fopen ( $url, "rb");
$contents = "";
while( true ) {
$data = fread($handle, 8192);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
}
fclose ($handle);
var_dump( $contents );
?>

I got 2 warnings when I run it:

Warning: fopen(): php_network_getaddresses: getaddrinfo failed: hostname nor servname provided, or not known in /usr/local/apache2/htdocs/heshun/kkk/zz.php on line 2

Warning: fopen(http://www.php.net): failed to open stream: Invalid argument in /usr/local/apache2/htdocs/heshun/kkk/zz.php on line 2

I have checked the relating conf 'allow_url_fopen' is 'on' in 'php.ini' more than once and I can be sure have no problems here because I run it by shell prompt with following when I log into my local net(BSD OS, PHP 4.3.10 ) :

test# php -a zz.php

It can work well ! why it happened this case? a bug? how can I resolve it ? I'm too urgent 🙁 and wait for help online

Hi

What exactly are you trying to do? Maybe there is another way of doing what you want do do. I've only ever used fopen to open files on my server, not an URL....but saying that, try do this

$url = "http://www.php.net/"; 

Note the trailing slash. That might be your problem

OK, I have found a way 🙂
use IP address as a substitute for domain.for previous example.

file_get_contents( "http://www.php.net/", "r" ); // failed
file_get_contents( "64.246.30.37", "r" ); // succeed

🙂 though I don't know the veriest reason of this case.
