本文實(shí)例講述了PHP數(shù)組對(duì)象與Json轉(zhuǎn)換操作。分享給大家供大家參考，具體如下：

代碼

?php
//數(shù)組轉(zhuǎn)對(duì)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;
}
//對(duì)象轉(zhuǎn)數(shù)組
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 $e;
}
//對(duì)象轉(zhuǎn)數(shù)組
function object_array($array){
  if(is_object($array)){
    $array = (array)$array;
  }
  if(is_array($array)){
    foreach($array as $key=>$value){
      $array[$key] = object_array($value);
    }
  }
  return $array;
}
//json到數(shù)組
function simple_json_parser($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 "現(xiàn)在的數(shù)組br>br>";
$arr=array(
  "name"=>"李小龍",
  "tel"=>"11111111111",
  "age"=>"12",
);
var_dump($arr);
echo "br>-------------------------------br>";
echo "br>br>數(shù)組轉(zhuǎn)對(duì)象br>br>";
$obj= arrayToObject($arr);
var_dump($obj);
echo "br>br>輸出對(duì)象屬性br>br>";
var_dump($obj->name);
echo "br>-------------------------------br>";
echo "br>br>對(duì)象轉(zhuǎn)數(shù)組br>br>";
$arr=object_array($obj);
var_dump($arr);
echo "br>br>輸出數(shù)組數(shù)值br>br>";
var_dump($arr["name"]);
echo "br>-------------------------------br>";
echo "br>br>Json到數(shù)組br>br>";
$json ='{"a":"哈哈","b":"我","c":"數(shù)","d":"一","e":3,"f":2,"g":1,"h":"別生氣了"}';
$arr=simple_json_parser($json);
var_dump($arr);
echo "br>官方換種方法br>";
echo "對(duì)象br>";
var_dump(json_decode($json));
$a=json_decode($json);
echo "br>屬性:";
echo $a->a;
echo "br>數(shù)組br>";
var_dump(json_decode($json,true));
echo "br>-------------------------------br>";
echo "br>br>數(shù)組到Jsonbr>br>";
var_dump($arr);
echo "br>";
var_dump(json_encode($json, JSON_HEX_APOS));

輸出

-------------------------------
現(xiàn)在的數(shù)組
array(3) { ["name"]=> string(9) "李小龍" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
-------------------------------
數(shù)組轉(zhuǎn)對(duì)象
object(stdClass)#1 (3) { ["name"]=> string(9) "李小龍" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
輸出對(duì)象屬性
string(9) "李小龍"
-------------------------------
對(duì)象轉(zhuǎn)數(shù)組
array(3) { ["name"]=> string(9) "李小龍" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
輸出數(shù)組數(shù)值
string(9) "李小龍"
-------------------------------
Json到數(shù)組
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "數(shù)" ["d"]=> string(3) "一" ["e"]=> string(1) "3" ["f"]=> string(1) "2" ["g"]=> string(1) "1" ["h"]=> string(12) "別生氣了" }
官方換種方法
對(duì)象
object(stdClass)#2 (8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "數(shù)" ["d"]=> string(3) "一" ["e"]=> int(3) ["f"]=> int(2) ["g"]=> int(1) ["h"]=> string(12) "別生氣了" }
屬性:哈哈
數(shù)組
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "數(shù)" ["d"]=> string(3) "一" ["e"]=> int(3) ["f"]=> int(2) ["g"]=> int(1) ["h"]=> string(12) "別生氣了" }
-------------------------------
數(shù)組到Json
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "數(shù)" ["d"]=> string(3) "一" ["e"]=> string(1) "3" ["f"]=> string(1) "2" ["g"]=> string(1) "1" ["h"]=> string(12) "別生氣了" }
string(136) ""{\"a\":\"\u54c8\u54c8\",\"b\":\"\u6211\",\"c\":\"\u6570\",\"d\":\"\u4e00\",\"e\":3,\"f\":2,\"g\":1,\"h\":\"\u522b\u751f\u6c14\u4e86\"}""
