php cURL function 301 error

Question

I am using this code :

function getUrl($url) {
if(@function_exists('curl_init')) {
    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; CrawlBot/1.0.0)');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT , 5);
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_ENCODING, "");
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    # required for https urls
    curl_setopt($ch, CURLOPT_MAXREDIRS, 15);            
    $site = curl_exec($ch);
    curl_close($ch);
    } else {
    global $site;
    $site = file_get_contents($url);
}
return $site;
};

But i see error 301 Moved Permanently.

What can i do to solve this ? can you give me the correct code please ?

Answer 1

CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set

You may try this:

Solution 1:

Set safe_mode = Off in your php.ini file (it's usually in /etc/ on the server). If that's already off, then look around for the open_basedir stuff in the php.ini file and comment that line (#open_basedir...). Restart apache server.

Solution 2:
If the above doesn't work (it should!) try this:

<?php
function geturl($url){

(function_exists('curl_init')) ? '' : die('cURL Must be installed for geturl function to work. Ask your host to enable it or uncomment extension=php_curl.dll in php.ini');

    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; CrawlBot/1.0.0)');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT , 5);
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    //curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_ENCODING, "");
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    # required for https urls
    curl_setopt($ch, CURLOPT_MAXREDIRS, 15);     

$html = curl_exec($curl);
$status = curl_getinfo($curl);
curl_close($curl);

if($status['http_code']!=200){
    if($status['http_code'] == 301 || $status['http_code'] == 302) {
        list($header) = explode("\r\n\r\n", $html, 2);
        $matches = array();
        preg_match("/(Location:|URI:)[^(\n)]*/", $header, $matches);
        $url = trim(str_replace($matches[1],"",$matches[0]));
        $url_parsed = parse_url($url);
        return (isset($url_parsed))? geturl($url):'';
    }
}
return $html;
}

?>

Answer 2

You might need to enable follow redirects using the location header flag:

curl -L <URL>
