PHP 警告：file_get_contents

Question

So 2 days ago I got this message:

PHP Warning: file_get_contents( http://example.com ): failed to open stream: Connection timed out in /home/server/map/index.php on line 30

This is what I've on line 29 and 30:

$url = 'http://example.com';

$string = file_get_contents($url);

The fun part is that I can see the external content on my local host. But not when I upload it to the server. Then I can only see the html + css included in the index.php file.

What I'm trying to do is to get all the available objects from the external website and post them on my website.

I've done it with a several other pages. But now encountered problems with some of them.

Anyone here who has any exemepl on how I can solve it with php. Possibly a completely different solution?

You can use the file_get_contents function remotely, but many hosts don't allow this. If you must use file_get_contents method, try to change default_socket_timeout option in PHP configuration in file php.ini or before your code insert:

ini_set('default_socket_timeout', 900); // 900 Seconds = 15 Minutes

This should help with connection timed out. But I would recommend using some PHP frameworks or just CURL: Client URL Library

For example:

function get_data($url) {   
    $ch = curl_init();  
    $timeout = 900; // 900 Seconds = 15 Minutes 
    curl_setopt($ch, CURLOPT_URL, $url);    
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);     
    $data = curl_exec($ch);     
    curl_close($ch);    
    return $data; 
}

The Usage:

$returned_content = get_data('http://www.angelaget.se/till-salu/');
