i have been working on a fileshare and i have been getting this error
Parse error: syntax error, unexpected T_EXIT in /home/a2078156/public_html/func/jspack.php on line 1
and wondered if anyone could revise it for me. thanks in advance

PHP Code:
<?phpif(!defined('CORE'))exit(0);function jspack(&$s){    $s preg_replace(array('/\r\n/s','/\n/s'),'',$s);}?>
