下面这句代码哪里错了

$aid = 11387;$_G['uid'] = 332;$tid =50;function aidencode($aid, $type = 0, $tid = 0) {	$s = !$type ? $aid.'|'.substr(md5($aid.md5('asdfasfas'.TIMESTAMP.$_G['uid']), 0, 8).'|'.TIMESTAMP.'|'.$_G['uid'].'|'.$tid : $aid.'|'.md5($aid.md5('asdfasfas').TIMESTAMP).'|'.TIMESTAMP;	return rawurlencode(base64_encode($s));}echo aidencode(11387);

回复讨论(解决方案)

$aid = 11387;$_G['uid'] = 332;$tid =50;function aidencode($aid, $type = 0, $tid = 0) {    $s = !$type ? $aid.'|'.substr(md5($aid.md5('asdfasfas'.TIMESTAMP.$_G['uid'])), 0, 8).'|'.TIMESTAMP.'|'.$_G['uid'].'|'.$tid  : $aid.'|'.md5($aid.md5('asdfasfas').TIMESTAMP).'|'.TIMESTAMP;    return rawurlencode(base64_encode($s));}echo aidencode(11387);
