 よくある質問

What is the difference between PHP short array syntax and legacy array() syntax?

PHP 5.4 introduced short array syntax using square brackets [] as an alternative to the traditional array() constructor. Both produce identical results at runtime. Short syntax is preferred in modern PHP codebases for its readability and reduced verbosity, while legacy syntax is necessary for projects that must support PHP 5.3 or earlier.
How does PHP handle JSON objects vs arrays differently?

JSON objects (key-value pairs enclosed in curly braces) map to PHP associative arrays with string keys and the => operator. JSON arrays (ordered lists in square brackets) map to PHP indexed arrays with automatic numeric keys. PHP uses the same array type for both, distinguishing them by whether keys are explicitly specified.
Why do PHP arrays use trailing commas?

Trailing commas after the last element in a PHP array are valid syntax and considered a best practice. They make version control diffs cleaner because adding a new element only changes one line instead of two. This convention was formalized in PHP and is widely adopted in PSR coding standards.
