php进行URL编码，解码

php在传递参数为url时, 可以使用

• urlencode()编码
• urldecode()解码

示例代码

<?php
    $v1 = "https://www.52dixiaowo.com/";
    echo "原始的url是:".$v1."<br>";
    $encode = urlencode($v1);
    echo "编码后的值是:".$encode."<br>";
    $decode = urldecode($encode);
    echo "解码后的值是:".$decode."<br>";
?>

输出结果

原始的url是:https://www.52dixiaowo.com/
编码后的值是:https%3A%2F%2Fwww.52dixiaowo.com%2F
解码后的值是:https://www.52dixiaowo.com/
