Standard Library

Zymba provides a rich set of built-in static classes accessed with the @ prefix. This chapter covers every built-in class with verified examples.

Class overview

Class	Methods	Purpose

@Number	42	Number formatting, type checks, base conversion, rounding
@Statistic	29	Statistical analysis — mean, median, mode, variance
@Date	31	Date/time — now, format, parse, components, timezone
@Var	30	JSON/PHP serialization, type inspection, cloning
@URI	20	URL encoding/decoding, query strings, parsing
@MIME	12	Base64 and MIME encoding

@XML	5	XML parsing and generation
@IO	61	File, directory, and stream operations
@HTTP	42	HTTP client/server — requests, headers, cookies
@DNS	7	DNS resolution and validation
@Path	15	File path manipulation
@System	8	System info: host, PID, memory usage
@Console	7	Logging and debug output
@Output	6	Output buffering control
@Crypt	22	Hashing, encryption, JWT, UUID generation
@Exception	—	Exception creation and stack traces
@Function	7	Function introspection and reflection
@Array	97	Array manipulation (covered in Arrays and Collections)

Practical patterns

JSON API response handler

ZYMBA

function $apiRequest($url, $method = "GET", $data = null) {
    $headers = ["Content-Type": "application/json"];
    $body    = ($data is null) ? null : @Var.toJSON($data);

    try {
        $response = @HTTP.requestBody($url, $method, $body, $headers);
        return @Var.fromJSON($response);
    } catch ($e) {
        return [error: $e.getMessage()];
    }
}

Data validation pipeline

ZYMBA

function $validateEmail($email) {
    $email = @String.trim($email);
    if (@String.isEmpty($email)) {
        return "Email is required";
    }
    if ([email protected]($email, "/^[^@\\s]+@[^@\\s]+\\.[^@\\s]+$/")) {
        return "Invalid email format";
    }
    return null;
}

Date range calculation

ZYMBA

$startOfMonth = @Date.create(1, @Date.getMonth(), @Date.getYear());
$endOfMonth   = @Date.create(
    @Date.getDaysInMonth(),
    @Date.getMonth(),
    @Date.getYear(),
    23, 59, 59
);

$formattedRange = @Date.format("Y-m-d", $startOfMonth)
    . " to "
    . @Date.format("Y-m-d", $endOfMonth);
