How to Convert a PHP Array to JSON
Create standards-compliant JSON from PHP array notation in three focused steps.
Choose JSON settings
Select indentation, numeric-key handling, key sorting, and optional Unicode or slash escaping.
Export valid JSON
Review the parsed structure, copy the result, or download a ready-to-use .json file.
A Purpose-Built PHP Array Parser
This tool does not execute the supplied PHP. A dedicated tokenizer reads array syntax, strings, numbers, booleans, null values, keys, nested arrays, trailing commas, and common comments before building the JSON structure.
Sequential numeric keys become JSON arrays in smart mode. Associative or non-sequential keys remain JSON objects so important identifiers are not silently discarded.
- Supports
[]andarray()syntax with nested values - Accepts assignments, return statements, and optional PHP tags
- Reports the location of unsupported syntax instead of running it

Professional Conversion for Real Data Work
Useful for configuration migrations, API payloads, fixtures, localization data, testing, and frontend handoffs.
Safer by design
The parser never evaluates functions, variables, expressions, includes, or executable PHP statements.
Structure-aware
Nested arrays and associative keys are preserved while sequential lists become natural JSON arrays.
Clear validation
Unsupported tokens and malformed arrays return a readable error with a nearby line and column.
Frequently Asked Questions
Important details about PHP array syntax and JSON conversion.
Does the converter execute my PHP code?
No. It uses a browser-side parser and never sends the input to PHP eval or the server.
Which PHP array formats are supported?
Both short [] arrays and classic array() notation are supported, including nested arrays and => keys.
Can I paste a variable assignment or return statement?
Yes. The parser can extract an array from common forms such as $config = [...] and return array(...);.
How are numeric PHP keys converted?
Smart mode produces a JSON array only when keys are sequential from zero. Other numeric keys are preserved in a JSON object.
Are PHP constants and function calls supported?
No. JSON has no equivalent for executable expressions. Replace constants, functions, objects, and variables with literal values before converting.
Is my PHP array uploaded?
No. Parsing, formatting, copying, and download creation happen locally in your browser.
