PHP数组对象与Json转换操作实例分析

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\"}""
