本篇文章给大家带来的内容是关于php代码加密解密类的示例（完整代码） ，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
php 代码加密类，大家可以根据自己的需求进行修改，原类如下，该实例在ubuntu下测试没有问题。
<?php
class Encryption{
private $c='';//存储密文
private $s='',$q1,$q2,$q3,$q4,$q5,$q6;//存储生成的加密后的文件内容
//如果不设置一个值，isset会表示不存在；
private $file='';//读取文件的路径
private $source='',$target='';
//构造函数，实例化时调用初始化全局变量；
public function __construct(){
//初始化全局变量
$this->initialVar();
//echo "hello \n";
}
/*
*@input $property_name,$value
*@output
* 魔法方法，对变量进行设置值；可根据需求进行处理。若直接去除if判断表示可用设置任何属性的值，包括不存在的属性；
*/
public function __set($property_name,$value){
//定义过的变量；
if(isset($this->$property_name)){
$this->$property_name = $value;
}else{
//异常处理，处理未声明的变量赋值；可根据需求进行处理。
throw new Exception("property does not exist");
}
}
//魔法方法 取出变量的值；
public function __get($property_name){
if(isset($this->$property_name)){
