PHP数组对象与Json转换操作实例分析
这篇文章主要介绍了PHP数组对象与Json转换操作,结合实例形式分析了php数组对象与json相互转换的实现方法及相关操作技巧,需要的朋友可以参考下
本文实例讲述了PHP数组对象与Json转换操作,分享给大家供大家参考,具体如下:
代码
- <?php
- //数组转对象
- function arrayToObject($e){
- if( gettype($e)!='array' ) return;
- foreach($e as $k=>$v){
- if( gettype($v)=='array' || getType($v)=='object' )
- $e[$k]=(object)arrayToObject($v);
- }
- return (object)$e;
- }
- //对象转数组
- function objectToArray($e){
- $e=(array)$e;
- foreach($e as $k=>$v){
- if( gettype($v)=='resource' ) return;
- if( gettype($v)=='object' || gettype($v)=='array' )
- $e[$k]=(array)objectToArray($v);
- }
- return $e;
- }
- //对象转数组
- function object_array($array){
- if(is_object($array)){
- $array = (array)$array;
- }
- if(is_array($array)){
- foreach($array as $key=>$value){
- $array[$key] = object_array($value);
- }
- }
- return $array;
- }
- //json到数组
- function simple_json_parser($json){
- $json = str_replace("{","",str_replace("}","", $json));
- $jsonValue = explode(",", $json);
- $arr = array();
- foreach($jsonValue as $v){
- $jValue = explode(":", $v);
- $arr[str_replace('"',"", $jValue[0])] = (str_replace('"', "", $jValue[1]));
- }
- return $arr;
- }
- echo "<br>-------------------------------<br>";
- echo "现在的数组<br><br>";
- $arr=array(
- "name"=>"李小龙",
- "tel"=>"11111111111",
- "age"=>"12",
- );
- var_dump($arr);
- echo "<br>-------------------------------<br>";
- echo "<br><br>数组转对象<br><br>";
- $obj= arrayToObject($arr);
- var_dump($obj);
- echo "<br><br>输出对象属性<br><br>";
- var_dump($obj->name);
- echo "<br>-------------------------------<br>";
- echo "<br><br>对象转数组<br><br>";
- $arr=object_array($obj);
- var_dump($arr);
- echo "<br><br>输出数组数值<br><br>";
- var_dump($arr["name"]);
- echo "<br>-------------------------------<br>";
- echo "<br><br>Json到数组<br><br>";
- $json ='{"a":"哈哈","b":"我","c":"数","d":"一","e":3,"f":2,"g":1,"h":"别生气了"}';
- $arr=simple_json_parser($json);
- var_dump($arr);
- echo "<br>官方换种方法<br>";
- echo "对象<br>";
- var_dump(json_decode($json));
- $a=json_decode($json);
- echo "<br>属性:";
- echo $a->a;
- echo "<br>数组<br>";
- var_dump(json_decode($json,true));
- echo "<br>-------------------------------<br>";
- echo "<br><br>数组到Json<br><br>";
- var_dump($arr);
- echo "<br>";
- var_dump(json_encode($json, JSON_HEX_APOS));
输出
------------------------------
现在的数组
- array(3) { ["name"]=> string(9) "李小龙" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
- -------------------------------
数组转对象
object(stdClass)#1 (3) { ["name"]=> string(9) "李小龙" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
输出对象属性
string(9) "李小龙"
对象转数组
array(3) { ["name"]=> string(9) "李小龙" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
输出数组数值
string(9) "李小龙"
Json到数组
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> string(1) "3" ["f"]=> string(1) "2" ["g"]=> string(1) "1" ["h"]=> string(12) "别生气了" }
官方换种方法
对象
object(stdClass)#2 (8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> int(3) ["f"]=> int(2) ["g"]=> int(1) ["h"]=> string(12) "别生气了" }
属性:哈哈
数组
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> int(3) ["f"]=> int(2) ["g"]=> int(1) ["h"]=> string(12) "别生气了" }
数组到Json
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> string(1) "3" ["f"]=> string(1) "2" ["g"]=> string(1) "1" ["h"]=> string(12) "别生气了" }
string(136) ""{\"a\":\"\u54c8\u54c8\",\"b\":\"\u6211\",\"c\":\"\u6570\",\"d\":\"\u4e00\",\"e\":3,\"f\":2,\"g\":1,\"h\":\"\u522b\u751f\u6c14\u4e86\"}""
