Last update on December 20 2024 10:25:13 (UTC/GMT +8 hours)

Write a PHP script to decode large integers.

Sample integer :
{"number": 123456789012345678901234567890}

Sample Solution:

PHP Code:

<?php
// Define a JSON string containing a large number as a string value
$json = '{"number": 123456789012345678901234567890}';

// Decode the JSON string into a PHP object
var_dump(json_decode($json));
?>

Output:

object(stdClass)#1 (1) {                                            
  ["number"]=>                                                      
  float(1.2345678901235E+29)                                        
}

Explanation:

In the exercise above,

• $json = ...: Define a JSON string containing a large number as a string value.
