[英]PHP in Javascript if mobile device
i have question, that i can't answer by myself. 我有一个问题,我自己不能回答。 I want to do the PHP code if a visitor is using mobile device.
如果访客正在使用移动设备,我想做PHP代码。 But, the problem is, that it execute the PHP code even if I'm one the PC.
但是,问题是,即使我是一台PC,它也会执行PHP代码。
if( /Android|webOS|iPhone|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
document.write("
<?php
if(isset($_COOKIE['web'])){
/* nothing */
}
else {
header("Location: /choose.php");
}
?>
");
}
Idea is to use PHP for detecting device, but some people told me that it's not working properly. 想法是使用PHP来检测设备,但有人告诉我它无法正常工作。 Thank's for response !
感谢您的回应!
Sure. 当然。 Because your php code is executed on the server side anyway.
因为无论如何,您的php代码都是在服务器端执行的。 And javascript on the client side.
和客户端上的javascript。
You can sniff the user agent server-side too: 您也可以在服务器端嗅探用户代理:
if( preg_match("/Android|webOS|iPhone|iPod|BlackBerry|IEMobile|Opera Mini/i",$_SERVER['HTTP_USER_AGENT']) && !isset($_COOKIE['web'])) {
die(header("Location: /choose.php"));
}
