Code Utils

To make our code more readable and clean, we'll use following global functions, that will be placed in utils.php file.

Pretty print arguments, that works like Python's print().

/**
 * Helper: format a value for array pretty-printing (Python-like)
 * - Nested arrays are supported recursively
 * - Integers are unquoted; other scalars are quoted and escaped
 */
function _pprint_format_for_array($value) {
    if (is_array($value)) {
        $formattedItems = array_map('_pprint_format_for_array', $value);
        return '[' . implode(', ', $formattedItems) . ']';
    }

    if (is_int($value) || is_float($value)) {
        return (string)$value;
    }

    if (is_bool($value)) {
        return $value ? 'True' : 'False';
    }

    if (is_null($value)) {
        return 'None';
    }

    // For other scalars/objects castable to string: quote and escape
    return "'" . addslashes((string)$value) . "'";
}

/**
 * Pretty print arguments
 * @param ...$args
 * @return void
 */
function pprint(...$args) {
    $parts = [];

    foreach ($args as $arg) {
        if (is_array($arg)) {
            // Format arrays like Python: [1, 2, 3] or ["a", "b", "c"] with nested arrays
            $parts[] = _pprint_format_for_array($arg);
        } elseif (is_bool($arg)) {
            // Format booleans like Python: True/False
            $parts[] = $arg ? 'True' : 'False';
        } elseif (is_null($arg)) {
            // Format null like Python: None
            $parts[] = 'None';
        } else {
            // Convert to string
            $parts[] = (string)$arg;
        }
    }

    echo implode(' ', $parts) . PHP_EOL;
}
