PHP捕捉错误并显示友好信息的方法
捕捉错误,不能使用try{...}catch(){}的方式,PHP里面的try{...}catch是需要自己抛出异常才能捕获的,区别于其他语言。
其次,可以使用如下的方法实现同样的效果:
error_reporting(0);//设置屏蔽系统错误提示,放页首
//$string = file_get_contents("index.html");//正常代码
echo 5/0;//改:5/8 //正常代码
//如果正常代码出错,则处理之:
$arr=error_get_last();//获取刚发生的错误信息,并返回数组,无错返回null.
if(isset($arr) ) //不为null,则表示出错了
{
echo "出错了,错误信息:";
print_r($arr); //具体错误信息,可根据需要修改。
exit;
}
--------------------------------------------------
【echo 5/8;】输出:
0.625
【echo 5/0;】输出:
出错了,错误信息:
Array (
[type] => 2
[message] => Division by zero
[file] => D:wampwwwsinaeditornewfile.php
[line] => 13
)
