利用网址传送资料_PHP
懂得HTML（超文本标识语言）的读者都应该知道在“＜FORM＞”的标签内可使用添加“GET”和“POST”参数的方式将资料送回HTTP服务器，其实，在PHP语言中我们同样可以使用“GET”及“POST”参数。除此之外，在网址上亦可以加上“GET”的资料，例如我们以下面的URL为例：
http://www.yourserver.com/download/down.php?id=1
http://www.yourserver.com/news/show.php?page=1
这些URL通常在网站的搜索引擎中会使用得最多，你看到的URL中都带了各种参数，目的是为了将资料传回http服务器以便找到相关信息。如果你觉得这个方式不好，笔者有另外一种方法可将传送的资料加在 URL 上，例如下面的网址：http://www.yourserver.com/vote/php/show.php/200107/2138/。
其对应的PHP源代码如下：
＜﹖
＄url＿variable ＝ split″/″ ＄PATH＿INFO
//取得网址后的资料
array＿splice＄url＿variable 01
//刪除第一个空白的记录
＄category＿id ＝ ＄url＿variable0
＄product＿id ＝ ＄url＿variable1
﹖＞
利用这种方法，你同样可以取得资料，不过要留意的是在URL上的资料次序是与“Array”（数组）内的次序一样，所以如果输出URL的资料有错，服务器在读入资料时就会出现错误，这需要我们加以注意。
另外如要输出中文字体到URL的话，你需要先用“rawurlencode”这个函数将中文字体转为RFC1738编码，方能达到你想要的显示效果。
