If you have cURL installed, you could use Curl to get the file, and manipulate the contents that way.

Here is the standard function I use for grabbing a remote page.

function doRequest($method, $url, $vars = '', $headers = '0') {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, $headers);
    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
    curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
    if ($method == 'POST') {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);
    }
    $data = curl_exec($ch);
    curl_close($ch);
    if ($data) {
        return $data;
    }
    else {
        return curl_error($ch);
    }
}

called with

doRequest('GET', '<url>');  

$vars would be either a string or an array of post variables, and headers either shows or hides headers from the webserver.  CURLOPT_TIMEOUT is set to 30, but you can change that to how many seconds you'd like to wait.

Hi,

One of my scripts are using wget to get external xml data

$fp = popen ("wget -O - '".$dst."' | cat","r");

Some time $dst host responds very slowly. And that time if I open another 
connection to same server the second request waits to complete wget 
operation.

I'm very noobie about this file operations. Is there any suggestion about this 
situation ?

Regards.

Sancar
