Converting JSON Objects to Associative Arrays in PHP

You can make JSON objects convert into associative arrays in PHP. To do this, the second parameter of the function json_decode needs to be set to the value true.

Let's try. Suppose we have the following JSON:

<?php
	$json = '{
		"a": 1,
		"b": 2,
		"c": 3
	}';
?>

Let's convert it into a PHP associative array:

<?php
	$data = json_decode($json, true);
?>

Let's check what we got:

<?php
	var_dump($data); // ['a' => 1, 'b' => 2, 'c' => 3]
?>

Convert the following JSON into a PHP associative array:

<?php
	$json = '{
		"ru": ["пн", "вт", "ср"],
		"en": ["mn", "tu", "wd"]
	}';
?>
