mysql_real_escape_string() ?

Lo all, Does mysql_real_escape_string exist? I've seen it in the manual pages, and to my understanding, it is the proper function to call on strings to escape them before inserting them into a database... I've used it as follows: $text[1] = mysql_real_escape_string($text[1]); $details[0] = mysql_real_escape_string($details[0]); $url[1] = mysql_real_escape_string($url[1]); However, it returns a error: Fatal error: Call to undefined function: mysql_real_escape_string() in D:\temp\grabnews.php on line 32 Now what???
