本文实例讲述了Zend Framework处理Json数据的方法。分享给大家供大家参考,具体如下:
JSON分隔符及意义
{} 用于实现对象的包含,对象都包含在大括号中
, 逗号用于分隔对象的不同属性,或者数组的元素
[] 用于存放数组,数组将存放在中括号中
: 用于表示键/值对的值,冒号前为键,冒号后为该键的值
JSON示例
{ "addressbook":{ "name":"Mary Lebow", "address":{ "street":"5 Main Street", "city":"San Diego,CA", "zip":91912 }, "phoneNumbers":[ "619 332-3452", "664 223-4667" ] }}
使用JSON
语法:$json = Zend_Json::encode($phpNative);
说明:其中,参数$phpNative为PHP常见的数据类型,可以是数组、对象或者其他类型的数据。
函数返回值$json为符合JSON格式的一个字符串。
示例:
<?phprequire_once("Zend/Json.php");$temp = array( "a"=>0, "b"=>1, "c"=>array( "c-1"=>21, "c-2"=>22, "c-3"=>23, ), "d"=>3);$json = Zend_Json::encode($temp);echo "临时数组内容为:";echo "<pre>";print_r($temp);echo "</pre>";echo "转换为JSON格式内容为:";echo "<pre>";print_r($json);echo "</pre>";
结果为:
临时数组内容为:Array( [a] => 0 [b] => 1 [c] => Array ( [c-1] => 21 [c-2] => 22 [c-3] => 23 ) [d] => 3)转换为JSON格式内容为:{"a":0,"b":1,"c":{"c-1":21,"c-2":22,"c-3":23},"d":3}
将JSON解码为普通数据
语法:$phpNative = Zend_Json::decode($json);
示例:
<?phprequire_once("Zend/Json.php");$json = "{ /"addressbook/":{ /"name/":/"zhangsan/", /"address/":{ /"street/":/"Chang an jie/", /"city/":/"BeiJing/", /"zip/":100001 }, /"phoneNumbers/":[ /"010-12345678/", /"010-11111111/" ] }}";echo "解码前为:";echo "<pre>";print_r($json);echo "</pre>";$native = Zend_Json::decode($json);echo "解码后为:";echo "<pre>";print_r($native);echo "</pre>";
输出结果为:
解码前为:{ "addressbook":{ "name":"zhangsan", "address":{ "street":"Chang an jie", "city":"BeiJing", "zip":100001 }, "phoneNumbers":[ "010-12345678", "010-11111111" ] }}解码后为:Array( [addressbook] => Array ( [name] => zhangsan [address] => Array ( [street] => Chang an jie [city] => BeiJing [zip] => 100001 ) [phoneNumbers] => Array ( [0] => 010-12345678 [1] => 010-11111111 ) ))
