本文实例讲述了Zend Framework动作助手Json用法。分享给大家供大家参考,具体如下:
Json的使用较简单,以下是文档给出的用法:
Json 用来解码和发送 JSON 响应;
当处理期望数据表响应的 AJAX 请求,JSON 响应迅速变成选择的响应。
JSON 可以立即在客户端被解析,从而快速执行。
JSON 动作助手完成以下任务:
如果布局是打开(enabled)的,则关闭(disable)它。
如果视图解析器(ViewRenderer)是打开的,则关闭它。
设置 'Content-Type' 响应头为 'application/json'。
缺省地,不需要等待动作执行完成,立即返回响应。
用法很简单:或者把它作为助手代理的方法来调用,或者调用 encodeJson() 和 sendJson() 方法的其中之一:
class FooController extends Zend_Controller_Action { public function barAction() { // do some processing... // Send the JSON response: $this->_helper->json($data); // or... $this->_helper->json->sendJson($data); // or retrieve the json: $json = $this->_helper->json->encodeJson($data); } }
Note: 保持布局 (Keeping Layouts)
如果你为 JSON 响应有分离的布局 - 也许把 JSON 封装到一些上下文 - 在 JSON 助手的每个方法接受第二个可选的参数:打开或关闭布局的 flag ,传递一个布尔 true 值将使布局保持打开:
class FooController extends Zend_Controller_Action { public function barAction() { // Retrieve the json, keeping layouts: $json = $this->_helper->json->encodeJson($data, true); } }

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
