What this developer tool does

It parses static literals and key/value structures, converts supported primitive types, and reports unsupported dynamic expressions rather than evaluating them.

Detect selected input format → parse supported literals → convert keys and primitive values → serialize output → report lossy or unsupported constructs.

Dynamic PHP expressions, function calls, object creation, constants resolved at runtime, and executable code cannot be evaluated by this browser-only converter.

Example

Input: ['name' => 'John', 'active' => true]

Output: valid JSON or JavaScript object syntax.

Tips for better output

Use static arrays for reliable conversion.
Quote all string keys.
Review output if the input contains constants or function calls.
