JSON To PHP

JSON To PHP is an npm package that converts JSON strings into PHP-style associative arrays. It is useful when working with JavaScript applications that need to generate PHP code for dynamic content or server-side processing.

Installation

You can install the package via npm:

npm install @timkit/json-to-php

Options:

interface Options {
    beautify?: boolean;
    indentLevel?: number;
    indentSize?: number;
    useTabs?: boolean;
}

The Options interface allows you to customize the behavior of the jsonToPhp function. Below are the available properties:

• beautify (optional, boolean): When set to true, the PHP array is formatted with line breaks and indentation for readability. Default is false.
• indentLevel (optional, number): Specifies the initial indentation level for the PHP array. Default is 0.
• indentSize (optional, number): Specifies the number of spaces for indentation when beautify is set to true. Ignored when useTabs is true Default is 4.
• useTabs (optional, boolean): When set to true, tabs are used for indentation instead of spaces. Default is false.

Usage

After installation, you can import and use jsonToPhp to convert JSON strings into PHP array format.

Basic Conversion

The jsonToPhp function takes a JSON string and converts it to a PHP-style associative array.

import {jsonToPhp} from '@timkit/json-to-php';

const jsonString = '{"name": "John", "age": 30}';

const phpArray = jsonToPhp(jsonString);
console.log(phpArray);
// ['name' => 'John', 'age' => 30]

Nested JSON Conversion

The package supports nested JSON objects, converting them into nested PHP arrays.

const nestedJson = '{"user": {"name": "Alice", "email": "[email protected]"}, "active": true}';

console.log(jsonToPhp(nestedJson));
// ['user' => ['name' => 'Alice', 'email' => '[email protected]'], 'active' => true]

Arrays in JSON

You can also convert JSON arrays into PHP arrays.

const jsonArray = '{"fruits": ["apple", "banana", "cherry"]}';

console.log(jsonToPhp(jsonArray));
// ['fruits' => ['apple', 'banana', 'cherry']]

Beautifying Output

You can beautify the output using the beautify option, which adds line breaks and indentation to make the PHP array more readable.

const jsonString = '{"name": "John", "address": {"city": "New York", "zip": "10001"}}';

console.log(jsonToPhp(jsonString, {beautify: true}));
// [
//     'name' => 'John',
//     'address' => [
//         'city' => 'New York',
//         'zip' => '10001'
//     ]
// ]

Indentation Level

The indentLevel option allows you to specify the inital indentation level for the PHP array.

console.log(jsonToPhp(jsonString, {beautify: true, indentLevel: 2}));
//        [
//            'name' => 'John',
//            'address' => [
//                'city' => 'New York',
//                'zip' => '10001'
//            ]
//        ]

You can adjust the indentation size:

console.log(jsonToPhp(jsonString, {beautify: true, indentSize: 2}));
// [
//   'name' => 'John',
//   'address' => [
//     'city' => 'New York',
//     'zip' => '10001'
//   ]
// ]

Using Tabs for Indentation

You can use tabs for indentation by setting the useTabs option to true.

console.log(jsonToPhp(jsonString, {beautify: true, useTabs: true}));
// [
// 	'name' => 'John',
// 	'address' => [
// 		'city' => 'New York',
// 		'zip' => '10001'
// 	]
// ]

Handling Different Data Types

The package supports different JSON data types including strings, numbers, booleans, and null values.

const jsonWithTypes = '{"isAdmin": true, "balance": 100.5, "preferences": null}';

console.log(jsonToPhp(jsonWithTypes));
// ['isAdmin' => true, 'balance' => 100.5, 'preferences' => null]

Edge Cases

Empty JSON

If you provide an empty JSON string, the package will return an empty PHP array.

console.log(jsonToPhp('{}'));
// []

Invalid JSON

If the provided string is not valid JSON, it will throw an error.

try {
    jsonToPhp('{invalid}');
} catch (error) {
    console.error('Invalid JSON format');
}
