if ($mode == 'fs') {
	$fs = @fsockopen($host, 80, $errno, $errstr, $timeout);
	if ( $fs !== false ) { 
		fwrite($fs, 'GET ' . $doc . " HTTP/1.1\r\n");
		fwrite($fs, 'Host: ' . $host . "\r\n");
		fwrite($fs, "Connection: Close\r\n\r\n");
		stream_set_blocking($fs, TRUE);
		stream_set_timeout($fs,$timeout); // Again the $timeout on the get
		$info = stream_get_meta_data($fs);
		$value = '';
		while ((!feof($fs)) && (!$info['timed_out'])) {
						$value .= fgets($fs, 4096);
						$info = stream_get_meta_data($fs);
						flush();
		}
		$value = substr($value, strpos($value,'a:2:{s:4:"stat";'));
		$pwg_mode = 'fs';
		if ( $info['timed_out'] === false ) return $value;
	}
}

3 - Sometime another solution: curl_exec See http://fr2.php.net/manual/en/curl.installation.php

if ($mode !== 'Err' and function_exists('curl_init')) {
	$ch = @curl_init();
	@curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
	@curl_setopt($ch, CURLOPT_URL, $url);
	@curl_setopt($ch, CURLOPT_HEADER, 1);
	@curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
	@curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
	$value = @curl_exec($ch);
	$header_length = @curl_getinfo($ch, CURLINFO_HEADER_SIZE);
	$status = @curl_getinfo($ch, CURLINFO_HTTP_CODE);
	@curl_close($value);
	if ($value !== false and $status >= 200 and $status < 400) {
			$value = substr($value, $header_length);
			$pwg_mode = 'ch';
			return $value;
	}
}
// No other solutions
$return["stat"] = 'failed';
if ($mode !== 'Err') { 
	echo "\n			<!== PiwigoPress_get: failed on file_get, fsockopen and cURL processes " 
		. "- No solution available on this website with its current configuration ==>\n";
}
$pwg_mode = 'Err';
return serialize($return);
