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

Given a string email address, extract the username.

Input: ‘[email protected]’
Output: priyank

Input: ‘[email protected]’
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= '[email protected]';

• 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";

<?php
  // Define Email Address
  $email  = '[email protected]';

  // Get the username by slicing string
  $username = strstr($email, '@', true);

  // Display the username
  echo $username."\n";
?>

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= '[email protected]';

• 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";

<?php
// Define Email Address
$email  = '[email protected]';

// Get the username by dividing mailid using'@' as separator
$parts = explode("@",$email);
$username = $parts[0];

// Display the username
echo $username."\n";
?>
