PHP program to decode the JSON string into an associative array

Program/Source Code:

The source code to decode the JSON string into an associative array is given below. The given program is compiled and executed successfully.

<?php
//PHP program to decode the Json string into 
//associative array.
$json = '{"Id1":101,"Id2":102,"Id3":103,"Id4":104}';
$ids = json_decode($json);

foreach ($ids as $key => $value)
{
    print ("Key: " . $key . " Value: " . $value . "<br/>");
}
?>

Output:

Key: Id1 Value: 101
Key: Id2 Value: 102
Key: Id3 Value: 103
Key: Id4 Value: 104

Explanation:

Here, we converted the JSON string into an associative array using library function json_decode() and assigned the result into $ids variable.

foreach($ids as $key => $value) 
{  
    print("Key: ".$key." Value: ".$value."
");  
}  

Here, we printed the key and values of the associative array using the foreach loop on the webpage.
