"#$%&'()*+,-./0123456789:;<=>"color: #ff0000">比较二者的结果：


1.  数字、大小写字母都不编码

2.  减号、点号、下划线  三个不编码

3. rawurlencode比urlencode多编码一个”加号“
关于JavaScript中escape与encodeURIComponent的区别：


> console.log(encodeURIComponent("统一注册1"));

%E7%BB%9F%E4%B8%80%E6%B3%A8%E5%86%8C1
> console.log(escape("统一注册1"));
%u7EDF%u4E00%u6CE8%u518C1

<"utf-8","gbk",urldecode("%E7%BB%9F%E4%B8%80%E6%B3%A8%E5%86%8C1")); 
echo "\n"; 
echo urldecode("%u7EDF%u4E00%u6CE8%u518C1"); 
// 使用下面的unescape可以
//echo iconv("utf-8","gbk",unescape("%u7EDF%u4E00%u6CE8%u518C1"); 
exit;

结果比较：


escape未编码的字符： *+-./@_   共7个


encodeURIComponent未编码的字符： !'()*-._~  共9个
