To follow ALL redirects using CURL brings up a lot of special cases. Here's a function that
takes everything into account (even javascript redirects)
<?php
function get_final_url( $url, $timeout = 5 )
{
$url = str_replace( "&", "&", urldecode(trim($url)) );
$cookie = tempnam ("/tmp", "CURLCOOKIE");
$ch = curl_init();
curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3)
Gecko/20041001 Firefox/0.10.1" );
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt( $ch, CURLOPT_ENCODING, "" );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );
$content = curl_exec( $ch );
$response = curl_getinfo( $ch );
curl_close ( $ch );
if ($response['http_code'] == 301 || $response['http_code'] == 302)
{
ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3)
Gecko/20041001 Firefox/0.10.1");
$headers = get_headers($response['url']);
$location = "";
foreach( $headers as $value )
{
if ( substr( strtolower($value), 0, 9 ) == "location:" )
return get_final_url( trim( substr( $value, 9, strlen($value) ) ) );
}
}
if ( preg_match("/window\.location\.replace\('(.*)'\)/i", $content, $value) ||
preg_match("/window\.location\=\"(.*)\"/i", $content, $value)
)
{
return get_final_url ( $value[1] );
}
else
{
return $response['url'];
}
}
?>
