README

This library will allow you to integrate the ZeroBounce API in your project using modern PHP7 and an OOP structure.

Prerequisites

You need an active account at https://zerobounce.net to use this library. From there, grab your API Key under API - Keys & Info.

Installation

To include this in your project, install it using Composer.

As we use return types and type hints, this library requires PHP 7.1 and works on all versions up until PHP 8.1

composer require nickdnk/zerobounce-php

Tests

Enter your API key into the ZeroBounceTest file and run it. This uses the test-emails supplied by ZeroBounce and will not cost you credit.

How to use

use nickdnk\ZeroBounce\Email;
use nickdnk\ZeroBounce\Result;
use nickdnk\ZeroBounce\ZeroBounce;

// You can modify the timeout using the second parameter. Default is 15.
// You an also pass proxy options to Guzzle using the third parameter.
// See https://docs.guzzlephp.org/en/stable/request-options.html#proxy for details.
$handler = new ZeroBounce('my_api_key', 30, ['https' => 'https://my-proxy-server']);

$email = new Email(
    
    // The email address you want to check
    'some-email@domain.com',
    
    // and if you have it, the IP address - otherwise null or omitted
    '123.123.123.123'

);

try {

    // Validate the email
    $result = $handler->validateEmail($email);
    
    if ($result->getStatus() === Result::STATUS_VALID) {
        
        // All good
        
        if ($result->isFreeEmail()) {
            
            // Email address is free, such as @gmail.com, @hotmail.com.
            
        }

        * supplied by ZeroBounce. All of these may be null or empty
