<?php
funencode('http://www.baidu.com?a=we fg&k=abc');
function funencode($s) {
print_r(urlencode($s));
echo '<p>';
print_r(rawurlencode($s));
}
輸出：
http%3A%2F%2Fwww.baidu.com%3Fa%3Dwe+fg%26k%3Dabc
http%3A%2F%2Fwww.baidu.com%3Fa%3Dwe%20fg%26k%3Dabc
說(shuō)明：
? 其他都一樣贪嫂，就是對(duì)于空格的處理不一樣
urlencode:把空格處理成+
rawurlencode:把空格處理成%20
