Array goto JSON

PHP Json_encode () is used to encode the variable JSON, which returns FALSE if the execution succeeds in returning the JSON data.

JSON to Array

The PHP Json_decode () function is used to decode a JSON-formatted string and convert it to a PHP variable.

$arr Array (' A ' = 1, ' b ' = = 2, ' c ' = 3, ' d ' = 4, ' e ' = 5 ');    echo json_encode ($arr);

results:   {"A": 1, "B": 2, "C": 3, "D": 4, "E": 5}

Vice versa.

Third-party interface parsing (StdClass object to array)

Recently, the development of the mall, the use of the logistics of the third-party API interface JSON data, often simply through the Json_decode method to obtain the numerical value is generally not an array,

It is a string of objects with Stdclass objec, and if we want to get the corresponding PHP array, we need to get it in the following ways.

//PHP StdClass Object goto ArrayfunctionObject_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; }

Because the Json_decode () function can accept two parameters:

When $data = Json_decode ($object); //Gets an object above the data type.

When $data = Json_decode ($object, ture); //The array is obtained.

$data= Json_decode ($json, ture);   

I use the second kind, simple also convenient, print data

Print_array ($data);

This is the same as the usual array, but also convenient to use, for example:

Echo $data [' Data '] [0] [' Traces '] [0] [' Desc ']; // [ Shanghai] [jiading] The earthquake emblem electronic received phone: no
