jqgrid显示不了数据

jqgrid显示不数据，请各位大大帮忙看看

 0) {			$total_pages = ceil($count / $limit);		} else {			$total_pages = 0;		}		if ($page > $total_pages)			$page = $total_pages;		$start = $limit * $page - $limit;		if ($startpage = $page;		$responce->total = $total_pages;		$responce->records = $count;		$i = 0;		while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {			$responce->rows[$i]['id'] = $row[id];			$opt = "修改";			$responce->rows[$i]['cell'] = array (				$row['sn'],				$row['title'],				$row['size'],				$row['os'],				$row['charge'],				$row['price'],				$opt			);			$i++;		}		//print_r($responce);		echo json_encode($responce);								function uniDecode($str, $charcode) {	$text = preg_replace_callback("/%u[0-9A-Za-z]{4}/", toUtf8, $str);	return mb_convert_encoding($text, $charcode, 'utf-8');}function toUtf8($ar) {	foreach ($ar as $val) {		$val = intval(substr($val, 2), 16);		if ($val 

回复讨论(解决方案)

$text = preg_replace_callback("/%u[0-9A-Za-z]{4}/", toUtf8, $str);
应为
$text = preg_replace_callback("/%u[0-9A-Za-z]{4}/", 'toUtf8', $str);

xuzuning大大， 'toUtf8'加两个单引号，我加了不行，我不知道是不是文件的编码有问题，本地测试的时候，有些Js文件我改一下编码，就显不了数据库的数据了

另外我直接输出结果

 0) {			$total_pages = ceil($count / $limit);		} else {			$total_pages = 0;		}		if ($page > $total_pages)			$page = $total_pages;		$start = $limit * $page - $limit;		if ($startpage = $page;		$responce->total = $total_pages;		$responce->records = $count;		$i = 0;		while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {			$responce->rows[$i]['id'] = $row["id"];			$opt = "修改";			$responce->rows[$i]['cell'] = array ($row['sn'],$row['title'],$row['size'],	$row['os'],	$row['charge'],	$row['price'],$opt);			$i++;		}				echo json_encode($responce);?>

可以显示了，我把那些转换函数都删除了
