PHP自动发邮件

自动发邮件使用了这个类http://bbs.php100.com/read-htm-tid-121431.html

因他用的php版本较老，用到了函数ereg_replace() 和 ereg()

解决方法

1、对于ereg_replace() 函数，替换为 strtr() 函数

语法不同点如下：

详情http://www.php.net/manual/zh/function.ereg-replace.php

详情http://www.w3school.com.cn/php/func_string_strtr.asp

2、对于ereg() 函数，替换为 preg_match() 函数

链接http://blog.163.com/yanli_xu/blog/static/1363672912011420101820393/

preg_match() 函数语法http://www.php.net/manual/zh/function.preg-match.php

修改完毕后，完整代码如下
