一个简单的PHP邮件发送类_PHP教程
推荐:PHP生成缩略图失真/不清晰的解决方法PHP生成缩略图失真/不清晰的解决方法 1.用imagecreatetruecolor和imageCopyreSampled函数分别取代imagecreate和imagecopyresized 2.给imagejpeg的第三个参数带上100(例:imagejpeg($ni,$toFile,100)) 建议将100设置为90.否则生成图片会很大,且效果跟90没有太大区别.
需要用PHP发送邮件,不想要phpmailer那么复杂,找来找去,总算找到了一个好用的,分享出来,代码如下.PHP邮件发送类,一共包含两个文件.
sent_mail.php
email.class.php
- <?php
- require_once ('email.class.php');
- //##########################################
- $smtpserver = "smtp.163.com";//SMTP服务器
- $smtpserverport =25;//SMTP服务器端口
- $smtpusermail = "xxx@163.com";//SMTP服务器的用户邮箱
- $smtpemailto = "xxx@qq.com";//发送给谁
- $smtpuser = "xxx@looklo.com";//SMTP服务器的用户帐号
- $smtppass = "*****";//SMTP服务器的用户密码
- $mailsubject = "PHP100测试邮件系统";//邮件主题
- $mailbody = "<h1> 这是一个测试程序 PHP100.com </h1>";//邮件内容
- $mailtype = "HTML";//邮件格式(HTML/TXT),TXT为文本邮件
- ##########################################
- $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.
- $smtp->debug = true;//是否显示发送的调试信息
- $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
- ?>

分享:揭秘优化php代码42种方法1.如果一个方法可静态化,就对它做静态声明。速率可提升至4倍。 2.echo比print快。 3.使用echo的多重参数(译注:指用逗号而不是句点)代替字符串连接。 4.在执行for循环之前确定最大循环数,不要每循环一次都计算最大值。 5.注销那些不用的变量尤其是大数组
