php如何判断是手机还是电脑

有时我们需要知道用户当前的设备，以便进行业务处理，例如pc就跳转pc站，手机就跳转手机站，下面介绍一种判断的方法。

首先php获取$_SERVER['HTTP_USER_AGENT']的值；
然后比对各个浏览器特定的字符串；
最后通过比对结果就能够判断是手机还是电脑了。

代码如下：

/**
 * 
 * 根据php的$_SERVER[&#39;HTTP_USER_AGENT&#39;] 中各种浏览器访问时所包含各个浏览器特定的字符串来判断是属于PC还是移动端
 * @author           discuz3x
 * @lastmodify    2014-04-09
 * @return  BOOL
 */
function checkmobile() {
 global $_G;
 $mobile = array();
//各个触控浏览器中$_SERVER[&#39;HTTP_USER_AGENT&#39;]所包含的字符串数组
 static $touchbrowser_list =array(&#39;iphone&#39;, &#39;android&#39;, &#39;phone&#39;, &#39;mobile&#39;, &#39;wap&#39;, &#39;netfront&#39;, &#39;java&#39;, &#39;opera mobi&#39;, &#39;opera mini&#39;,
