How to validate an email programmatically
Introduction
I want to validate an email address programmatically, but I don't understand how it works. I would like to know what's the best way (or any way) of validating an email address.
Get the email address using a form on the front end (HTML forms)
To collect data from users using an email address, you need to send them a form on the front end. HTML is embedded in the browser and sent to the server, which can then send back an HTML page containing all of the information collected. The data can be stored in a database and used by other programs.
Validate the email field to make sure it's not empty.
Check if the email field is not empty.
Use a regular expression to check if the email is valid, for example:
```php
$email = filter_input(INPUT_GET, 'email', FILTER_VALIDATE_EMAIL);
If you don't have access to this function, use PHP's getLastError() method instead of FILTER_VALIDATE_EMAIL().
Validate the email address by using a regular expression.
The email address validation is a fairly simple process. We're going to use a regular expression to check if the email address is valid by using FILTER_VALIDATE_EMAIL.
First, you'll need to ensure that your form is loaded with data:
You may also want to add some comments about why this field is required or how it should be filled out (for example: "This field should only have one character in it").
Check that the domain has MX records.
To validate that the email programmatically, you can use a tool like DNS Guru. This tool looks up MX records for your domain or subdomain and compares them with those stored in DNS servers around the world. It will show you which server receives mail from your domain, as well as how long it takes before this happens (the delay time).
You can also check whether there are any problems with your MX records: if one doesn't exist, then you'll get an error message when trying to send an email through your account.
The final step is actually testing if we can send an email to that address by sending an email with a unique token, and then checking if that token is properly received.

Send the test message: python send_email.py "Test message"
Check for success: python send_email_test.py -b TOKEN
A simple way to validate an email using PHP is to use FILTER_VALIDATE_EMAIL, which validates value as an e-mail address. On the other hand, if you want to actually check if an email is deliverable, you need to create a script that will check the MX records of the domain and then check whether sending an email succeeds or not.

In order for this function to work properly on your server platform, there are some prerequisites: First off all - make sure that it's available in your operating system or environment; secondly - make sure that PHP supports arrays; thirdly - make sure that you have installed all required libraries (like GD library) before proceeding further with this article!
Conclusion
A lot of websites are built on top of PHP, so if you're not familiar with the language and want to try out this solution for yourself, then I encourage you to do so.
