How to Extract the User Name from the Email ID Using PHP

Extracting the username from an email ID in PHP is a straightforward task. Typically, the username is the part of the email address before the ”@” symbol. You can achieve this using PHP’s string manipulation functions.

Here’s a step-by-step guide to extract the username:

1. Use explode() Function: This function splits a string by a specified delimiter and returns an array of strings. For email extraction, you can split the string at the ”@” character.

2. Get the Username: The username will be the first element of the array returned by explode().

Here’s a simple example demonstrating how to do this:

<?php
// Sample email address
$email = "[email protected]";

// Split the email address by the "@" character
$parts = explode("@", $email);

// Check if the email address is valid and has the "@" character
if (count($parts) == 2) {
    // The username is the first part
    $username = $parts[0];
    echo "Username: " . $username;
} else {
    echo "Invalid email address";
}
?>

Explanation:#

1. explode("@", $email): This splits the email address into an array, where $parts[0] contains the username and $parts[1] contains the domain.

2. count($parts) == 2: Ensures that the email address contains exactly one ”@” symbol.

Edge Cases:#

• Invalid Emails: Handle cases where the email doesn’t contain an ”@” symbol or contains multiple ”@” symbols.
• Empty Strings: Ensure that the $email variable is not empty before performing operations.

Alternative Using strstr():#

If you prefer a different approach, you can also use the strstr() function to get the part before the ”@” and then further process it:

<?php
$email = "[email protected]";

// Get the part before the "@" symbol
$username = strstr($email, '@', true);

echo "Username: " . $username;
?>

In this example:

• strstr($email, '@', true) returns the part of the string before the ”@” symbol.
