携帯電話デバイスを判別するための PHP コード

<meta charset="utf-8">这是PHP判断手机设备函数代码，复制到PHP函数库中调用:<?phpfunction is_mobile() {	$user_agent = $_SERVER ['HTTP_USER_AGENT'];	$mobile_browser = Array (			"mqqbrowser", // 手机QQ浏览器			"opera mobi", // 手机opera			"juc",			"iuc", // uc浏览器			"fennec",			"ios",			"applewebKit/420",			"applewebkit/525",			"applewebkit/532",			"ipad",			"iphone",			"ipaq",			"ipod",			"iemobile",			"windows ce", // windows phone			"240×320",			"480×640",			"acer",			"android",			"anywhereyougo.com",			"asus",			"audio",			"blackberry",			"blazer",			"coolpad",			"dopod",			"etouch",			"hitachi",			"htc",			"huawei",			"jbrowser",			"lenovo",			"lg",			"lg-",			"lge-",			"lge",			"mobi",			"moto",			"nokia",			"phone",			"samsung",			"sony",			"symbian",			"tablet",			"tianyu",			"wap",			"xda",			"xde",			"zte" 	);	$is_mobile = false;	foreach ( $mobile_browser as $device ) {		if (stristr ( $user_agent, $device )) {			$is_mobile = true;			break;		}	}	return $is_mobile;}?>这是调用代码，可以加上if判断:<?php if(is_mobile()):?>设置手机端的内容<?php endif; ?>
