PHP判断手机端、PC端、微信代码实例

在这里博主为大家分享了PHP判断的两个实例，一是PHP判断是手机端还是PC端，二是PHP判断是否是微信浏览器，供大家参考，具体内容如下
1、判断是否是手机端

<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">isMobile</span><span class="hljs-params">()</span> </span>{
  <span class="hljs-comment">// 如果有HTTP_X_WAP_PROFILE则一定是移动设备</span>

    <span class="hljs-keyword">return</span> <span class="hljs-keyword">true</span>;
  }
  <span class="hljs-comment">// 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息</span>
  <span class="hljs-keyword">if</span> (<span class="hljs-keyword">isset</span>($_SERVER[<span class="hljs-string">'HTTP_VIA'</span>])) {
    <span class="hljs-comment">// 找不到为flase,否则为true</span>

    <span class="hljs-keyword">false</span> || (strpos($_SERVER[<span class="hljs-string">'HTTP_ACCEPT'</span>], <span class="hljs-string">'vnd.wap.wml'</span>) &lt; strpos($_SERVER[<span class="hljs-string">'HTTP_ACCEPT'</span>], <span class="hljs-string">'text/html'</span>)))) {
      <span class="hljs-keyword">return</span> <span class="hljs-keyword">true</span>;
    }
  }
  <span class="hljs-keyword">return</span> <span class="hljs-keyword">false</span>;
}

function isMobile() {

// 如果有HTTP_X_WAP_PROFILE则一定是移动设备

if (isset($_SERVER['HTTP_X_WAP_PROFILE'])) {

return true;

}

// 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息

if (isset($_SERVER['HTTP_VIA'])) {

// 找不到为flase,否则为true

return stristr($_SERVER['HTTP_VIA'], "wap") ? true : false;

}

// 脑残法，判断手机发送的客户端标志,兼容性有待提高。其中'MicroMessenger'是电脑微信

if (isset($_SERVER['HTTP_USER_AGENT'])) {

$clientkeywords = array('nokia','sony','ericsson','mot','samsung','htc','sgh','lg','sharp','sie-','philips','panasonic','alcatel',

'lenovo','iphone','ipod','blackberry','meizu','android','netfront','symbian','ucweb','windowsce','palm','operamini','operamobi',

'openwave','nexusone','cldc','midp','wap','mobile','MicroMessenger');

// 从HTTP_USER_AGENT中查找手机浏览器的关键字

if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) {

return true;

}

// 协议法，因为有可能不准确，放到最后判断

if (isset ($_SERVER['HTTP_ACCEPT'])) {

// 如果只支持wml并且不支持html那一定是移动设备

// 如果支持wml和html但是wml在html之前则是移动设备

if ((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false) && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') ===

false || (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))) {

return true;

}

return false;

}

2、判断是否是微信内置浏览器

<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">isWeixin</span><span class="hljs-params">()</span> </span>{
  <span class="hljs-keyword">if</span> (strpos($_SERVER[<span class="hljs-string">'HTTP_USER_AGENT'</span>], <span class="hljs-string">'MicroMessenger'</span>) !== <span class="hljs-keyword">false</span>) {
    <span class="hljs-keyword">return</span> <span class="hljs-keyword">true</span>;
  } <span class="hljs-keyword">else</span> {
    <span class="hljs-keyword">return</span> <span class="hljs-keyword">false</span>;
  }
}

function isWeixin() {

if (strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') !== false) {

return true;

} else {

return false;

}
