How to extract the user name from the email ID using PHP ?

  • Difficulty Level : Hard
  • Last Updated : 26 May, 2021

Given a string email address, extract the username.

Input: ‘priyank@geeks.com’
Output: priyank

Input: ‘princepriyank@gfg.com’
Output: princepriyank

Approach 1: Using PHP strstr() to extract the username from the email address.

In this, “@” symbol is the separator for the domain name and user name of the email address. The strstr() PHP function is used to search for the first occurrence of a string i.e. “@” inside another string i.e. email address to get the username as result.

  • Step 1: Define a variable and store the value of the email address in it.

    $email= 'priyank@geeks.com';
  • Step 2: Get the username by slicing the string till the first occurrence of ‘@’ using this line



    $username=strstr($email,'@',true);
  • Step 3: Display the username using an echo statement.

    echo $username."\n";

Example:

PHP




<?php
  // Define Email Address
  $email  = 'priyank@geeks.com';
  
  // Get the username by slicing string
  $username = strstr($email, '@', true);
  
  // Display the username
  echo $username."\n";
?>
Output
priyank

Approach 2:  Using PHP explode() function.

In this, we harness the fact that the “@” symbol is the separator for the domain name and user name of the email address. So explode() is used to break a string into an array by a separator “@”.

  • Step 1: Define a variable email and store the value of email address in it.

    $email= 'princepriyank@geeks.com';
  • Step 2: Get the username by exploding (dividing) the string using ‘@’ as a separator and store the first part in the variable username.

    $parts = explode("@",$email);
    $username = $parts[0];
  • Step 3: Display the username using this code.

    echo $username."\n";

Example:

PHP




<?php
// Define Email Address
$email  = 'princepriyank@geeks.com';
  
// Get the username by dividing mailid using'@' as separator
$parts = explode("@",$email);
$username = $parts[0];
  
// Display the username
echo $username."\n";
?>
Output
princepriyank
