在現(xiàn)如今，作為PHP網(wǎng)站開(kāi)發(fā)程序員需要接觸到各種程序接口，比如網(wǎng)站修改密碼使用smtp類(lèi)輕松的發(fā)送電子郵件，首先smtp類(lèi)發(fā)送郵件的方法其實(shí)很簡(jiǎn)單，也很穩(wěn)定，類(lèi)是別人已經(jīng)寫(xiě)好的了，你只需要調(diào)用就行了。幾行簡(jiǎn)單的配置就能發(fā)郵件，下面我們一起來(lái)看一下吧。

發(fā)送郵箱的php文件

最后還有smtp類(lèi)無(wú)法發(fā)送郵件解決方法：
偶然發(fā)現(xiàn)網(wǎng)站后臺(tái)自動(dòng)發(fā)送郵件功能不能用了，報(bào)這個(gè)錯(cuò)誤：
Tryingtosmtp.XX.com:25Error:Cannotconnencttorelayhostsmtp.XX.comError:()Error:Cannotsendemailtoweb@daixiaorui.comstate
大概意思是：無(wú)法connenct中繼主機(jī)smtp.XX.com錯(cuò)誤：()錯(cuò)誤：無(wú)法發(fā)送電子郵件
找了很多資料后終于找到了解決方案，不是smtp類(lèi)的問(wèn)題，而就是linux配置的問(wèn)題。原來(lái)是服務(wù)器的php.ini禁用了fsockopen函數(shù)。
打開(kāi)空間下的php.ini文件，linux空間一般都可以自定義php.ini，所以根目錄下面一般會(huì)有這個(gè)文件。
有兩個(gè)地方可能禁用此函數(shù)：
1.allow_url_fopen=On查看等于后面是否為ON，如果為OFF時(shí)函數(shù)將被禁用
2.disable_functions=fsockopenpfsockopen(我的就是這樣)這里應(yīng)該去掉前面的“fsockopen”。使之變成：disable_functions=pfsockopen
