That is my coding. What I need to do is if the script finds the words "There are no reported closures."  it will stop running and not email anything out.

I hope someone can help me.

Narrow your problem down and please, give us a better description of what it is your trying to do.

I am trying to make an if statement that does the following but I can't figure out how to word it or where to place it.

if $message == There are no reported closures.  then DIE;

Now I think it needs to be before this part.

[code]//Send an email if there is a new event
if ($send_email) {
  print ("Sending the message below to " . $email_recip . ", from \"" . $email_from . "\" <" .$email_from_addr . ">.\n" . $event_message . "\n");
  mail ($email_recip, $email_subject, $event_message, "From: \"" . $email_from . "\" <" .$email_from_addr . ">");
  print ("Found a new event:\nRegion: " . $curr_events[$curr_event_num][1] . "\nHighway(s): " . $curr_events[$curr_event_num][0] . "\nReason: " . $curr_events[$curr_event_num][2] . "\n==========\n");
}
[/code]

So that it stops the script from sending the email.

Does this help any?

So is the 3rd Party Script forum the place where bad people go?  It's not a 3rd Party Script. It was a script created for me which you won't find anyplace else online that anyone else can use. The only problem is the guy who created it for me got shipped overseas for 6 months.
