If the result of calling the function is true, it is the mobile terminal.

Sometimes, we will configure different domain name access based on the differences between the mobile terminal and the PC terminal. In this regard, we can determine the domain name currently being accessed, and then determine the terminal device, and jump to the corresponding domain name based on the judgment. As follows:

// 判断当前访问地址
$url = $_SERVER[&#39;HTTP_HOST&#39;];
if($url == &#39;移动端url&#39;) {	//移动端访问地址
    if(!isMobile()) {
	// 终端是PC，跳转到PC端url
    	echo &#39;<script>location.href="https://PC端url地址"</script>&#39;;
    	exit;
    }
} else {	                //pc访问地址
    if(isMobile()) {
        // 终端是移动端，跳转到移动端url
        echo &#39;<script>location.href="https://移动端访问地址"</script>&#39;;
        exit;
    }
}
