用PHP即時捕捉PHP原始碼中的錯誤并發送email通知-php手册-PHP中文网

開發php的朋友都知道,其實最擔心的就是程序中出現一些異常或錯誤,這些狀況如果輸出到用戶的螢幕會把用戶給嚇壞,甚至為此丟了工作,如果不輸出到螢幕就得想辦法記錄到日誌中,但是似乎不是每個人都有查看錯誤日誌的習慣,爲了解決這個尷尬的問題,所以我寫了這段代碼,其用意就是當我們寫的php程式出錯的時候把錯誤內容捕捉出來然後發到我們的email內.
先看效果:
<span style="color: #008080;">Define</span>('SYS_DEBUG',<span style="color: #0000ff;">false</span><span style="color: #000000;">);
</span><span style="color: #0000ff;">IF</span><span style="color: #000000;">(SYS_DEBUG) {
</span><span style="color: #008080;">ini_set</span>('display_errors','on'<span style="color: #000000;">);
</span><span style="color: #008080;">Error_reporting</span>(<span style="color: #ff00ff;">E_ALL</span>);<span style="color: #008000;">//</span><span style="color: #008000;">上線后使用該設定Error_reporting(E_ERROR | E_WARNING | E_PARSE);</span>
}<span style="color: #0000ff;">Else</span><span style="color: #000000;">{
</span><span style="color: #008080;">ini_set</span>('display_errors','off'<span style="color: #000000;">);
</span><span style="color: #008080;">Error_reporting</span>(0<span style="color: #000000;">);
}

</span><span style="color: #008000;">//</span><span style="color: #008000;">錯誤捕捉</span>
<span style="color: #008080;">Register_shutdown_function</span>('Fun::Error'<span style="color: #000000;">);

</span><span style="color: #0000ff;">Class</span><span style="color: #000000;"> Fun{

</span><span style="color: #008000;">/*</span><span style="color: #008000;">*
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);
