请问前辈们能帮我从这个日志对比找出出错页面打不开的原因吗
不然错误500 你们一般是怎么排除找出bug的呢？
找到原因了
public function get_list($tid = 0,$limit = 0,$offset = 0)
{
if(empty(intval($tid))){
return false;
}
if(empty(intval($limit))){
return false;
}
上面两个变量判断改成下面代码就运行正常了
if(!ctype_digit($tid))return false;
if(!ctype_digit($limit))return false;
这个写法日志和页面都没报错 我就想不通是php语法问题还是ci的问题
