解析錯誤：語法錯誤，意外的T_CATCH在...行65上？

Question

錯誤發生在第65行：}趕上（例外$ E）{

<?php 

require "includes/connect.php"; 



function generateCode($length = 5) 
{ 
    $characters = 'bcdfghjkmnpqrstvwxyz'; 
    $string = ''; 

    for ($i = 0; $i < $length; $i++) { 
     $string .= $characters[rand(0, strlen($characters) - 1)]; 
    } 
    return $string; 
} 


$msg = ''; 


if($_POST['email']) { 

    // Requested with AJAX: 
    $ajax = ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest'); 


    try { 

     if(!filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)){ 
      throw new Exception('Invalid Email!'); 
     } 

     if($ajax){ 
      die('{"status":1}'); 
     } 

     $unique_code = ""; 
     $inserted = false; 

     // Keep looping until we've inserted a record 
     while(!$inserted) { 

      // Generate a code 
      $unique_code = generateCode(); 

      // Check if it exists 
      if ($result = $mysqli->query("SELECT unique_code FROM coming_soon_emails WHERE unique_code = '$unique_code'")) { 

      // Check no record exists 
      if ($result->num_rows == 0) { 

       // Create new record 
       $mysqli->query("INSERT INTO coming_soon_emails (email,unique_code) VALUES ('" . $mysqli->real_escape_string($_POST['email']) . "','$unique_code')"); 

       // Set inserted to true to ext loop 
       $inserted = true; 

       // Close the result object 
       $result->close(); 
      } 
     } 

    } catch (Exception $e){ 

     if($ajax){ 
      die(json_encode(array('error'=>$e->getMessage()))); 
     } 

     $msg = $e->getMessage(); 
     die($msg); 
    }  

} else { 
    // Quit if we can't check the database 
    die('Something went wrong with select'); 
}

你的括號不匹配。 您的while循環在結尾處沒有正確的匹配大括號（在兩個if語句之後）......只需在catch行之前添加一個}即可。

你應該得到類似Notepad ++的東西來寫PHP！
