JSON to PHP Array — Free Online JSON to PHP Converter

What Is a PHP Array?

A PHP array is an ordered map that associates keys with values. Unlike JSON, which has separate object and array types, PHP uses a single array construct for both indexed lists and associative maps.

// Indexed array
['Apple', 'Banana', 'Cherry']

// Associative array
['name' => 'Alice', 'email' => '[email protected]']

PHP arrays support nesting, mixed key types, and heterogeneous values — making them the primary data structure in PHP applications.

PHP Array Syntax: Legacy vs. Short

// Legacy syntax (PHP 4+)
array('key' => 'value', 'name' => 'Alice')

// Short syntax (PHP 5.4+) — recommended
['key' => 'value', 'name' => 'Alice']

This tool outputs short array syntax ([]), which is the modern standard.

What Is JSON?

JSON (JavaScript Object Notation) is a lightweight, human-readable text format defined by RFC 8259. It uses key-value pairs and ordered lists to represent structured data.

{"name": "Alice", "age": 30, "active": true}

JSON vs. PHP Array — Key Differences

JSON-to-PHP Type Mapping

Why Convert JSON to PHP Array?

json_decode() vs. This Tool

PHP has a built-in json_decode() function. Understanding when to use each approach matters.

Using json_decode() (Runtime)

<?php
$json = '{"name": "Alice", "age": 30}';
$data = json_decode($json, true);
// $data = ['name' => 'Alice', 'age' => 30]

Using This Tool (Code Generation)

<?php
// Hardcoded PHP array — no runtime parsing needed
$data = [
   'name' => 'Alice',
   'age' => 30,
   'active' => true,
   'roles' => ['admin', 'editor'],
   'address' => [
       'city' => 'New York',
       'zip' => '10001',
   ],
];

Privacy by Design

All processing runs entirely in your browser. No data is uploaded to any server. Your JSON data never leaves your device.

Complete Examples

Example

Input JSON:

{
   "id": 1,
   "name": "Alice",
   "email": "[email protected]",
   "active": true,
   "roles": ["admin", "editor"],
   "address": {
       "city": "New York",
       "zip": "10001"
   }
}

Output PHP Array:

[
   'id' => 1,
   'name' => 'Alice',
   'email' => '[email protected]',
   'active' => true,
   'roles' => ['admin','editor',],
   'address' => [
       'city' => 'New York',
       'zip' => '10001',
   ],

]

Example — Array of Records

Input JSON:

[
   {"id": 1, "name": "Alice"},
   {"id": 2, "name": "Bob"},
   {"id": 3, "name": "Charlie"}
]

Output PHP Array:

[
   ['id' => 1,'name' => 'Alice',],
   ['id' => 2,'name' => 'Bob',],
   ['id' => 3,'name' => 'Charlie',],
]

Example — Nested Objects with Mixed Types

Input JSON:

{
   "product": "Laptop",
   "price": 999.99,
   "inStock": true,
   "tags": ["electronics", "computers"],
   "specs": {
       "cpu": "M2",
       "ram": 16,
       "storage": null
   }
}

Output PHP Array:

[
   'product' => 'Laptop',
   'price' => 999.99,
   'inStock' => true,
   'tags' => ['electronics','computers',],
   'specs' => [
       'cpu' => 'M2',
       'ram' => 16,
       'storage' => null,
   ],
]

Real-World Use Cases

Laravel Database Seeder

<?php
// database/seeders/UserSeeder.php
namespace Database\Seeders;
use Illuminate\Database\Seeder;

class UserSeeder extends Seeder
{
   public function run(): void
   {
       $users = [
           ['id' => 1,'name' => 'Alice','email' => '[email protected]','active' => true,],
           ['id' => 2,'name' => 'Bob','email' => '[email protected]','active' => false,],
       ];
       \DB::table('users')->insert($users);
   }
}

PHPUnit Data Provider

<?php
// tests/Feature/UserTest.php
use PHPUnit\Framework\TestCase;

class UserTest extends TestCase
{
   public static function userInfoProvider(): array
   {
       return [
           ['id' => 1,'name' => 'Alice','email' => '[email protected]','active' => true,],
       ];
   }
   #[DataProvider('userInfoProvider')]
   public function testUserIsActive(array $user): void{
       $this->assertTrue($user['active']);
   }
}

WordPress Configuration

$theme_config = [
   'site_name' => 'My Blog',
   'posts_per_page' => 10,
   'sidebar' => true,
   'social_links' => [
       'twitter' => 'https://twitter.com/example',

Frequently Asked Questions (FAQ)

• Does the tool upload my data?

  No. All conversion happens locally in your browser using JavaScript. Your data never leaves your device.

• What PHP array syntax does the tool output?

  The tool outputs short array syntax ([]) using single-quoted string keys ('key' => value). This is the modern PHP 5.4+ standard.

• What JSON types are supported?

  All standard JSON types: strings, integers, floats, booleans, null, objects (converted to associative arrays), and arrays (converted to indexed arrays). Nested structures are handled recursively.

• Can I use this for Laravel seeders?

  Yes. The output is valid PHP array syntax that works directly in Laravel database seeders, factory definitions, and PHPUnit data providers.

• What is the difference between json_decode() and this tool?

  json_decode() parses JSON at runtime. This tool generates static PHP array code you can paste directly into .php files. Use json_decode() for dynamic data (APIs, files); use this tool for static data (seeders, configs, test fixtures).

• Does the tool support PHP's legacy array() syntax?

  No. The tool outputs short syntax ([]) only, which is the recommended format since PHP 5.4.

• Is there a file size limit?

  The tool processes data entirely in your browser. Files up to 10 MB typically convert without issues on modern hardware.

• Can I use this on mobile?

  Yes. The tool is responsive and works on smartphones and tablets.

• Does the tool handle invalid JSON?

  The tool displays an "Invalid JSON" badge when the input is malformed. Fix the JSON and try again.
