Ok so I'm still having problems. This is what I need:
I want a function to echo a message if a username does not pass my requirments.

  - Only letters and / or numbers
 - Must start with a letter (not a number)
 - No spaces

The current code is not working for me. Please help
}else if (!(eregi('/[^\w\'\"\@\-\.\]/i', '',($_POST["username"])))){
		echo "<p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><br />Please go back, USERNAME is only allowed to have letters and numbers with NO SPACES MUST BE BETWEEN 5 to 10 characters.<p>&nbsp;</p><p>&nbsp;</p><a href='javascript:javascript:history.go(-1)'>Click here to go back to previous page</a>";
