Paylaştım hocam onuda teşekkürler yardımınız için

Şu kodu silip hata çıktısına bakınız.

@error_reporting(E_ALL ^ E_NOTICE);
@ini_set('display_errors', true);
@ini_set('html_errors', false);
@ini_set('error_reporting', E_ALL ^ E_NOTICE);

Muhtemelen şurada hata var. Ayrıca gereksiz bir kod diyebiliriz. Bunu silip yeniden deneyin olmadı gündüz vakti anydesk atarsanız yeni bir captcha dosyası oluştururuz.

function clean_url($url)
{
if ($url == '') {
return;
}

$url = str_replace("http://", "", $url);
if (strtolower(substr($url, 0, 4)) == 'www.') {
$url = substr($url, 4);
}
$url = explode('/', $url);
$url = reset($url);
$url = explode(':', $url);
$url = reset($url);

return $url;
}

if (clean_url($_SERVER['HTTP_REFERER']) != clean_url($_SERVER['HTTP_HOST'])) {
return;
}

Önemli hata: Yakalanmadı Hata: /var/www/vhosts/sesligoruntulu.com/httpdocs/captcha.php'de tanımsız clean_url() işlevine çağrı: 10 Yığın izleme: /var/www/vhosts/sesligoruntulu'da #0 {main} atıldı .com/httpdocs/captcha.php 10. satırda

böyle bir hata var sanırım
bu kodu da sildim

function clean_url($url)
{
if ($url == '') {
return;
}

$url = str_replace("http://", "", $url);
if (strtolower(substr($url, 0, 4)) == 'www.') {
$url = substr($url, 4);
}
$url = explode('/', $url);
$url = reset($url);
$url = explode(':', $url);
$url = reset($url);

return $url;
}

if (clean_url($_SERVER['HTTP_REFERER']) != clean_url($_SERVER['HTTP_HOST'])) {
return;
}

[/QUOTE]

Hata çıktısı dediğim bu kodda kodu sildikten sonra düzelmedi mi?

hayır hocam yine göstermiyor
