Как я могу правильно назвать функцию?

Question

Кодекс:

$url = $_POST['url']; 
$team = $_POST['team']; 
$user = $_POST['user']; 
$regip = $_SERVER[REMOTE_ADDR]; 
$low_user = strtolower($user); 
$up_user = strtoupper($user); 

Функция XSS фильтр, который я нашел в Интернете:

function xss_clean_team($team) 
{ 
$team = str_replace(array('&','<','>'), array('&','<','>'), $team); 
$team = preg_replace('/(&#*\w+)[\x00-\x20]+;/u', '$1;', $team); 
$team = preg_replace('/(&#x*[0-9A-F]+);*/iu', '$1;', $team); 
$team = html_entity_decode($team, ENT_COMPAT, 'UTF-8'); 
$team = preg_replace('#(<[^>]+?[\x00-\x20"\'])(?:on|xmlns)[^>]*+>#iu', '$1>', $team); 
$team = preg_replace('#([a-z]*)[\x00-\x20]*=[\x00-\x20]*([`\'"]*)[\x00-\x20]*j[\x00-\x20]*a[\x00-\x20]*v[\x00-\x20]*a[\x00-\x20]*s[\x00-\x20]*c[\x00-\x20]*r[\x00-\x20]*i[\x00-\x20]*p[\x00-\x20]*t[\x00-\x20]*:#iu', '$1=$2nojavascript...', $team); 
$team = preg_replace('#([a-z]*)[\x00-\x20]*=([\'"]*)[\x00-\x20]*v[\x00-\x20]*b[\x00-\x20]*s[\x00-\x20]*c[\x00-\x20]*r[\x00-\x20]*i[\x00-\x20]*p[\x00-\x20]*t[\x00-\x20]*:#iu', '$1=$2novbscript...', $team); 
$team = preg_replace('#([a-z]*)[\x00-\x20]*=([\'"]*)[\x00-\x20]*-moz-binding[\x00-\x20]*:#u', '$1=$2nomozbinding...', $team); 
$team = preg_replace('#(<[^>]+?)style[\x00-\x20]*=[\x00-\x20]*[`\'"]*.*?expression[\x00-\x20]*\([^>]*+>#i', '$1>', $team); 
$team = preg_replace('#(<[^>]+?)style[\x00-\x20]*=[\x00-\x20]*[`\'"]*.*?behaviour[\x00-\x20]*\([^>]*+>#i', '$1>', $team); 
$team = preg_replace('#(<[^>]+?)style[\x00-\x20]*=[\x00-\x20]*[`\'"]*.*?s[\x00-\x20]*c[\x00-\x20]*r[\x00-\x20]*i[\x00-\x20]*p[\x00-\x20]*t[\x00-\x20]*:*[^>]*+>#iu', '$1>', $team); 
$team = preg_replace('#</*\w+:\w[^>]*+>#i', '', $team); 
do 
{ 
$old_data = $team; 
$team = preg_replace('#</*(?:applet|b(?:ase|gsound|link)|embed|frame(?:set)?|i(?:frame|layer)|l(?:ayer|ink)|meta|object|s(?:cript|tyle)|title|xml)[^>]*+>#i', '', $team); 
} 
while ($old_data !== $team); 
return $team; 
} 

Так что да, я хочу, чтобы фильтровать ввод данных пользователем с помощью этой функции, как я могу сделать это правильно? :)

Answer 1

ли это через следующий код

echo xss_clean_team($user);
