百度搜索结果url加密算法 PHP源码

使用 命令行解释脚本

php url.php

PHP语言的全局变量要在函数中 global $x, $y, $ascii, $data; 全局申明才能使用
重新改了函数版，和 Python就更加象了

<?php
//$ascii码表x,y位置
$ascii = [
    0 => [ ' ', '!', '"', '#', '$', '%', '&', "'", '(', ')', '*', '+', ',', '-', '.', '/' ],
    1 => [ '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', ':', ';', '<', '=', '>', '?' ],
    2 => [ '@', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L','M', 'N', 'O'  ],
    3 => [ 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', '[', '\\',']', '^', '_' ],
    4 => [ '`', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o' ],
    5 => [ 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '{', '|', '}', '~', ' ' ]
    ];
