how to create username from email address provided - PHP

php email extract username
Luke picture Luke · Jun 5, 2009 · Viewed 12.5k times · Source

I have a signup page on my website where a user must provide a email address and password only.

I want to be able to create a username for this user automatically by using the first part of the email provided;

User supplies gordon@yourdomain.com, i want to make username 'gordon'

I don't need explanation on how to create form or submission of data to database, just the code to extract data from email provided, and if necessary, if duplicate occurs add number to end.

Hope this makes sense, seems like a basic function but couldn't find examples of it anywhere on net!

This is not a good idea, just use their full email address. The following email addresses could be different people, but they will become the same under your system.

[email protected]
[email protected]

Adding a number to the end will make the user remember something unique to your system and cause much confusion on their end.
