在php中我们要如何检查 url 链接是否已经有参数,添加 ? 或 &呢,下面我来分享一个函数。
 代码如下 复制代码
$old_url = $_SERVER["REQUEST_URI"];
  
//检查链接中是否存在 ?
$check = strpos($old_url, '?');
  
//如果存在 ?
if($check !== false)
{
    //如果 ? 后面没有参数,如 hindex.php?
    if(substr($old_url, $check+1) == '')
    {
        //可以直接加上附加参数
        $new_url = $old_url;
    }
    else    //如果有参数,如:index.php?ID=12
    {
        $new_url = $old_url.'&';
    }
}
else    //如果不存在 ?
{
    $new_url = $old_url.'?';
}
  
echo $new_url;
