我正在尝试使用 选择 id 并将其$_GET[]分配给一个变量,但是它不起作用。当我尝试$_GET[]直接回显它工作正常时,ID 显示在页面上,但是当我将它分配给一个变量并尝试回显它时,它不会工作。例如这不起作用:
$sel_hotel = $_GET[];
echo $sel_hotel; 
代码看起来很好,没有任何问题,但它只是不将该值传递给变量我相信我的 php.ini 文件可能有问题,但我不确定。我正在使用 PHP 版本 5.4.3。请帮忙 。非常感谢你
<?php 
if(isset($_GET['hotl'])){
 $sel_hotel = $_GET['hotl']; 
 $sel_hotel ="";
 echo   $sel_hotel;
}elseif(isset($_GET['room'])){
 $sel_room = $_GET['room'];
 $sel_room ="";
 echo $sel_room;
}else{
$sel_hotel ="";
$sel_room ="";
}
echo  $sel_hotel;
?>
