Use PHP to instantly capture errors in the PHP source code and send email notifications, javaemail sent

Friends who develop PHP know that in fact, the most worrying thing is the error in the program Some exceptions or errors. If these conditions are output to the user's screen, the user will be frightened and even lose their job. If they are not output to the screen, they have to find a way to record them in the log, but it seems that not everyone has the ability to check the errors. In order to solve this embarrassing problem, I wrote this code. Its purpose is to capture the error content when the php program we wrote makes an error and send it to our email.
Let’s take a look at the effect first: 

<span>Define</span>('SYS_DEBUG',<span>false</span><span>);
</span><span>IF</span><span>(SYS_DEBUG) {
</span><span>ini_set</span>('display_errors','on'<span>);
</span><span>Error_reporting</span>(<span>E_ALL</span>);<span>//</span><span>上線后使用該設定Error_reporting(E_ERROR | E_WARNING | E_PARSE);</span>
}<span>Else</span><span>{
</span><span>ini_set</span>('display_errors','off'<span>);
</span><span>Error_reporting</span>(0<span>);
}

</span><span>//</span><span>錯誤捕捉</span>
<span>Register_shutdown_function</span>('Fun::Error'<span>);

</span><span>Class</span><span> Fun{

</span><span>/*</span><span>*
通用出錯處理
参数:
要輸出的內容,是否終止執行程序
說明:
有傳值時該函式可以用來輸出自定義的錯誤內容
另外還可以配合Register_shutdown_function實現自動抓取錯誤內容,並將抓取的錯誤內容發送到Email內
Register_shutdown_function的機制是程序執行完畢或中途出錯時調用函數
如果是自動抓取錯誤時被調用,則會取得最後一次出錯的內容,如果發現沒有錯誤內容則跳出
返回:
內容會被直接輸出至螢幕或Email內
用法:
Fun::Error('錯誤內容');
Fun::Error('錯誤內容',False);
