This tutorial shows you on how to extract the domain name from an email address in different programming languages, such as PHP, Java, VB .NET, C#, Python, Javascript and Ruby programming language. The below sample code is useful when you need to extract the domain name to be supplied into [FraudLabs Pro REST API](https://www.fraudlabspro.com/developer/api/screen-order) (for **email_domain** field) or any other project requirements.

## Extract Domain in PHP

```
<?php
$email = 'user@example.com';
$domain = substr($email, strpos($email, '@') + 1);
?>
```

## Extract Domain in Java

```
String email = "user@example.com";
String domain = email .substring(email .indexOf("@") + 1);
```

## Extract Domain in VB.NET

```
Dim email As String = "user@example.com"
Dim startIndex As Integer = email.IndexOf("@")
Dim endIndex As Integer = email.IndexOf(".", startIndex)

Dim domain As String = email.SubString(startIndex + 1, endIndex)
```

## Extract Domain in C#

```
string email = "user@example.com";
int indexOfAt = email.IndexOf('@');
string domain = email.Substring(indexOfAt + 1);
```

## Extract Domain in Python

```
email = 'user@example.com'
domain = email.split('@')[1]
```

## Extract Domain in Javascript

```
const emailAddress = "example@example.com";

// Extract the domain
const domain = emailAddress.split('@')[1];

console.log(domain);
```

## Extract Domain in Ruby

```
email_address = "example@example.com"

# Extract the domain using a regular expression
domain = email_address.match(/@(.+)$/)
puts domain[1]
```
