Class PaymentTransactionId

The PaymentTransactionId class implements the Stringable interface and represents a payment transaction ID. It has a single private property $value which holds the value of the transaction ID and a constructor that sets the value of $value upon instantiation. The class also has a __toString() method that returns the string representation of the PaymentTransactionId object.

Constructor

__construct(string $transactionId): void

The constructor takes in a single parameter $transactionId of type string. It validates if the string is a valid UUID (Universally Unique Identifier) and throws an InvalidArgumentException if it is not. If the string is valid, it sets the value to the $value property.

Methods

__toString(): string

The __toString() method returns the string representation of the PaymentTransactionId object.

Example Usage

$transactionId = new PaymentTransactionId('123e4567-e89b-12d3-a456-426655440000');
echo $transactionId;

// Output: 123e4567-e89b-12d3-a456-426655440000
