urlencode的有关问题奇怪了
urlencode的问题奇怪了，请教大家
我想把字符串“('baidu')中”用php的urlencode函数输出这样的字符串：('baidu')%e4%b8%ad
但实际上输出：%28%27baidu%27%29，
我在百度搜索关键字：在线url编码,结果排名第三的是：百度应用的一个url编码小程序，在那个用utf8编码就可以输出：
('baidu')%e4%b8%ad，请问为什么啊？
当然字符串当中汉字“中”，生成的不一样无所谓，因为我的源代码是utf8,的，所以，但是我就奇怪了怎么才能让php
的urlencode()函数，不编码逗号和小括号呢？
------解决方案--------------------
string urlencode ( string $str )
返回字符串，此字符串中除了 -_. 之外的所有非字母数字字符都将被替换成百分号（%）后跟两位十六进制数，空格则编码为加号（+）。
百度那个并不严格，如果你不希望转码括号，可以对转码后的结果用 str_replace('%28', '(', $enstr) 替换过来
------解决方案--------------------
百度那个就是不准,我用过.
