After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

✨ Key Features

⚠️ Important Notice & Limitations

Please Note: This package performs a detailed technical analysis of an email address. However, it cannot 100% guarantee that a specific mailbox actually exists or is active. The only definitive way to verify this is by sending an email with a confirmation link.

📦 Installation

Install the package easily via Composer.

⚙️ System Requirements

Minimum Requirements

Recommended for Mass Validation

🚀 Quick Start

📖 Basic Usage

Understanding the Result

The validate() method returns an associative array with the following keys:

Key Type Description
email string The submitted email address.
is_valid bool true if the email passes all key validations (format and domain).
domain_valid bool true if the domain has valid MX or A DNS records.
is_disposable bool true if the email is from a known disposable service.
pattern_valid bool true if email passes pattern filtering (fast rejection).
pattern_status string Pattern validation status: passed, rejected, or warning.
matched_pattern string|null Regex pattern that matched (if rejected), null if passed.
smtp_valid bool|null true if SMTP validation confirms mailbox exists, false if failed, null if disabled.
smtp_response string|null SMTP server response (if SMTP validation enabled), null if disabled.
smtp_status_code string|null Detailed SMTP status code (if SMTP validation enabled), null if disabled.
timestamp string When the validation was performed.
