Hello Epvpers.

Maybe any1 can tell me what this code does?

<?php 
$sql_inject_1 = array(";","'","%",'"'); #Whoth need replace 
$sql_inject_2 = array("", "","","""); #To wont replace 
$GET_KEY = array_keys($_GET); #array keys from $_GET 
$POST_KEY = array_keys($_POST); #array keys from $_POST
$COOKIE_KEY = array_keys($_COOKIE); #array keys from $_COOKIE 
/*begin clear $_GET */ 
for($i=0;$i<count($GET_KEY);$i++) 
{ 
$_GET[$GET_KEY[$i]] = str_replace($sql_inject_1, $sql_inject_2, HtmlSpecialChars($_GET[$GET_KEY[$i]])); 
} 
/*end clear $_GET */ 
/*begin clear $_POST */ 
for($i=0;$i<count($POST_KEY);$i++) 
{ 
$_POST[$POST_KEY[$i]] = str_replace($sql_inject_1, $sql_inject_2, HtmlSpecialChars($_POST[$POST_KEY[$i]])); 
} 
/*end clear $_POST */ 
/*begin clear $_COOKIE */ 
for($i=0;$i<count($COOKIE_KEY);$i++) 
{ 
$_COOKIE[$COOKIE_KEY[$i]] = str_replace($sql_inject_1, $sql_inject_2, HtmlSpecialChars($_COOKIE[$COOKIE_KEY[$i]])); 
} 
/*end clear $_COOKIE */

Seems like a text code.

It replaces chars like % in an other char.

It goes through a text and changes them.
