Installation

Usage

Here’s how to use the EmailValidator class:

Basic Validation

You can validate a single email address as follows:

<?php

require 'vendor/autoload.php'; // Autoload files using Composer

use EzeanyimHenry\EmailValidator\EmailValidator;

// Create a new instance of the EmailValidator
$emailValidator = new EmailValidator();

// Validate a single email address
$result = $emailValidator->validate('test@example.com');

if ($result['isValid']) {
    echo "The email is valid.";
} else {
    echo "Error: " . $result['message'];
}

Validating Multiple Email Addresses

To validate multiple email addresses at once, simply pass an array:

<?php

require 'vendor/autoload.php'; // Autoload files using Composer

use EzeanyimHenry\EmailValidator\EmailValidator;

// Create a new instance of the EmailValidator
$emailValidator = new EmailValidator();

// Validate multiple email addresses
$emails = [
    'test@example.com',
    'invalid-email',
    'user@mailinator.com',
];

$results = $emailValidator->validate($emails);
foreach ($results as $email => $result) {
    echo "$email: " . ($result['isValid'] ? "Valid" : "Invalid - " . $result['message']) . "\n";
}

Configuration Options

You can customize the validator's behavior by passing configuration options when creating the instance:

<?php

require 'vendor/autoload.php'; // Autoload files using Composer

use EzeanyimHenry\EmailValidator\EmailValidator;

// Create a new instance with custom configuration
$emailValidator = new EmailValidator([
    'checkMxRecords' => true,
    'checkBannedListedEmail' => true,
    'checkDisposableEmail' => true,
    'checkFreeEmail' => false,
    'checkEmailExistence' => true,
    'checkMailServerResponsive' => true,
    'checkGreylisting' => true,
    'checkCatchAll' => false,
]);

// Validate an email
$result = $emailValidator->validate('test@example.com');

Error Handling

The validate() method returns an associative array containing the validation result and a message. You can check if the email is valid by accessing the isValid key, and you can get the error message from the message key.

if (!$result['isValid']) {
    echo "Validation failed: " . $result['message'];
}

Testing

To run the tests, ensure you have PHPUnit installed. You can run the tests with the following command:
