求救。php处理批量删除图片

foreach($_POST['id'] as $k=>$id){$id=intval($id);DB::query("DELETE FROM ".DB::table('abc')." WHERE id='$id' LIMIT 1 ");

$result = DB::query("SELECT * FROM ".DB::table('abc')." where id='$id' and pic!=NULL LIMIT 1 ");		$rows = mysql_fetch_assoc($result);		@unlink($rows[pic]);

回复讨论(解决方案)

信息可以删除了，但是图片删除不掉

SELECT pic FROM ".DB::table('abc')." where id='$id'
