Question

如果我的所有$ _GET值都不为null，我试图让一块php运行。我的代码如下：

if (!isset($_REQUEST['name']) 
 || !isset($_REQUEST['number']) 
 || !isset($_REQUEST['section']) 
 || !isset($_REQUEST['email'])){

  //open files and write
  $email_file = fopen("emails","a+");
  $url_file = fopen("urls","a+");
  $courses_file = fopen("courses","a+");
  fwrite($email_file, $_REQUEST['email'] . "\n");
  fwrite($url_file, $url . "\n");
  fwrite($courses_file, $_REQUEST['name'] . " " . $_REQUEST['number'] . " " . $_REQUEST['section'] . "\n");
}

这似乎根本不起作用。无论我传递的是什么，都没有任何内容写入我的文件。如果我删除if语句，代码适用于编写文件，所以我知道它在我的条件中的某个地方。

if (!empty($_GET['name']) 
 && !empty($_GET['number']) 
 && !empty($_GET['section']) 
 && !empty($_GET['email'])){

  //open files and write
  file_put_contents('emails.txt', $_GET['email'] . "\n", FILE_APPEND | LOCK_EX);

  file_put_contents('urls.txt', $url . "\n", FILE_APPEND | LOCK_EX);  // Where does $url come from??? It's not coming from the $_GET params.

  file_put_contents('courses.txt', $_GET['name'] . " " . $_GET['number'] . " " . $_GET['section'] . "\n", FILE_APPEND | LOCK_EX);
}

检查$ _REQUEST值是否为null的代码无效。有任何想法吗？
