How to convert json into array object in php

PHP is a widely used programming language used to develop web applications and websites. One of the key aspects is processing data, especially JSON data. JSON (JavaScript Object Notation) is a formatted data exchange language commonly used for data exchange between web applications. In PHP, the process of converting JSON data into an array object is very common and very simple.

To convert JSON data into an array object in PHP, you can use PHP's built-in function: json_decode(). This function accepts a JSON formatted string as argument and converts it into a PHP array object.

The following is a simple example demonstrating how to convert JSON data into a PHP array object:

$json = '{"name":"Tom", "age":26, "city":"New York"}';

$array = json_decode($json, true);

print_r($array);

In the above code, we define a JSON string and use json_decode() Function converts it to a PHP array object. The first parameter of the function is a JSON string, and the second parameter is a Boolean value. When set to true, an associative array will be returned instead of an object.

The output results are as follows:

Array
(
    [name] => Tom
    [age] => 26
    [city] => New York
)

In the above code, we can see that we successfully converted the JSON data into a PHP array object. This array contains all data information in the JSON data.

If you want to convert JSON data to a PHP object instead of an array, please set the second parameter of the json_decode() function to false or do not pass the second parameter. The following is an example:

$json = '{"name":"Tom", "age":26, "city":"New York"}';

$obj = json_decode($json);

print_r($obj);

The output result is as follows:

stdClass Object
(
    [name] => Tom
    [age] => 26
    [city] => New York
)

In the above code, we use the json_decode() function to convert JSON data into a PHP object. This object contains all attribute information in the JSON data.

Summary

In PHP, it is very common to convert JSON data into array objects. This process can be easily accomplished using the built-in json_decode() function. By introducing JSON data, we can more conveniently use data exchange between web applications. What we need to remember is that when using the json_decode() function, the second parameter determines the type of return. If the second parameter is not passed, an object will be returned.
