Zend Framework高级功能详解

1. 使用PHP处理JSON

Zend_Json类提供了一种简单的编码器/解码器机制，用于在JSON和PHP变量之间进行转换。以下是一个使用Zend_Json的示例代码：

public function jsonAction() { $this->getHelper('ViewRenderer')->setNoRender(); //Simulate a JSON input value $jsonInput = '[0,1,2,3]'; //Decode JSON to a PHP array $phpArray = Zend_Json::decode($jsonInput); //Do a PHP operation shuffle($phpArray); //Encode the data for output $jsonOutput = Zend_Json::encode($phpArray); //Get the response object and set content type HTTP header $response = $this->getResponse(); $response->setHeader('Content-Type', 'application/json'); //Make sure the JSON is the only output data $response->clearBody(); //Set the response body to the JSON code
