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

)

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
