1、php密码生成类实例_ 本文实例讲解并描述了php实现的密码生成类及其应用方法，分享给大家供大家参考。具体分析如下： 一、php密码生成类功能： 1.可设定密码长度。 2.可设定要生成的密码个数，批量生成。 3.可以指定密码的规章，字母，数字，特别字符等。 二、用法： GeneratePassword.class.php类文件如下： ?12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970
