PHP Array to JSON Converter

Transform any PHP array syntax into valid JSON. Supports both short ([...]) and long (array(...)) array syntax. Handles associative arrays with string keys, indexed arrays, nested arrays, and mixed types. Booleans are parsed from true/false, null from null. The output is properly indented JSON.

Use Cases

• Config Migration — Convert PHP config files to JSON format
• API Development — Transform PHP array responses to JSON payloads
• Data Portability — Move from PHP-based config to JSON-based config
• Cross-Language — Share PHP data structures with non-PHP applications

Example

Input:

<?php
return [
  'app' => [
    'name' => 'MyApp',
    'version' => '1.0.0',
    'debug' => false,
    'servers' => ['192.168.1.1', '192.168.1.2'],
    'database' => [
      'host' => 'localhost',
      'port' => 5432,
    ],
  ],
];

Output:

{
  "app": {
    "name": "MyApp",
    "version": "1.0.0",
    "debug": false,
    "servers": ["192.168.1.1", "192.168.1.2"],
    "database": {
      "host": "localhost",
      "port": 5432
    }
  }
}
