The following code has ! (exclamanation point) !eregi and !trim what does
that mean?

if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,6}$", $email)) {
  echo "<p>It appears you entered an invalid email address</p><p><a
href='javascript: history.go(-1)'>Click here to go
back</a>.<br/><br/><br/>If Above Link Doesn't Work Please Use 'Back Arrow'
On Your Browser.<br/><br/><br/><br/><br/><br/></p>";

 elseif (!trim($name)) {
  echo "<p>Please go back and enter a Name</p><p><a href='javascript:
history.go(-1)'>Click here to go back</a>.<br/><br/><br/>If Above Link
Doesn't Work Please Use 'Back Arrow' On Your
Browser.<br/><br/><br/><br/><br/><br/></p>";

Thanks

! inverts the result of the function:

eregi() returns true if it finds the requested string -> !eregi()
returns true if it does not find the string

trim() returns the string without trailing spaces -> !trim() return
true if the string is empty.
