Basically, somone enters two (1 digit) numbers in separate fields (call them A and
. Then they choose to add, minus, times or divide these 2 numbers.
The add, minus, times and divide each have a code number (call this C).
The code number chosen is multiplied by one of 3 other numbers chosen at random (call this M).
Then this is displayed on the screen like this:
A (C times M) B
So, if you enter the numbers 3 and 7 and you choose times (*) for which the code number is 2. The other number (M) chosen is 2. 5 times 2 = 8
So this is displayed:
3 8 7
Assuming you understand this...
How can I do it in PHP?
I may be able to offer some DDF$...

No need for your forum $$$
Two questions though:
1. Does the user need to chose M, or is M randomly selected by the script?
2. What are the code numbers (C) for the +, -, * and \ ?
Attached is a single PHP that you can upload directly to your server to test by calling through your browser. I've tested it and it works but I may not have understood your requirements correctly...
What I have done is:
a. User keys in 1st variable
b. User keys in 2nd variable
c. User selects operator - "+, -, * or /". I've set + to be 1, - to be 2, * to be 3 and / to be 4
d. User selects 1 of 3 "random" numbers
e. User clicks submit
The following will be displayed:
a c*d b
Regards.
But I would like the number M or you called it d, to be chosen randomly...
And then, if the code could be sent in an email as oppossed to being displyed on screen?
Thanks loads!!
Copy everything below and paste it into a file ending with .php - it now uses a PHP generated random number instead of relying on the user to select a number...
Appreciate you can tell me if it's OK in testing (I've tested it myself) ...

I'de like it to choose a random number out of 3 that are defined in the script...Not just 3 random number... I didn't make that clear...
And then it sends the little number code thing out in an email... It shouldn't display it on screen at all....
Or does the script already do that?
sorry for being missing in action for the past month - i had to juggle time between my mba exams and my project at work.
in any event, the script doesn't do what you require. do you still need it? just reply and i'll get it going for you.
once again, sorry for not closing this off before i disappeared.
regards.
finally managed to squeeze some time to look into this...
1. copy everything into a file named rand.php - if you want to change this file name, you'll have to reflect the change in the script too - only 1 instance
2. the codes for +,-,*,/ is defined in the script - it's easy for you to change the values - currently, i've used "1" for +, "2" for -, "3" for *, and "4" for /
3. the 3 random numbers are also defined in the script - it's easy for you to change the values - currently, i've used $randomno1 = 7, $randomno2 = 8 and $randomno3 = 9
4. the script will send the results by email to a specified address - you'll have to change 3 variables in the script - $to = "recipient@domain.com", $subject = "The Subject" and $from = "From:sender@domain.com";
it should work fine. do give me a shout if you need anything changed - i won't be able to respond immediately as i don't drop by everyday...
I think its working but theres a few things...
1. Does the from email address need to be real or can I just put anything there?
2. Can you make a quick change so that if everything goes well it will say so?
Cheers!

in the mail command,
1. $to needs to be a real address - otherwise the email doesn't get sent
2. $from can be a fake address
3. to tell the user that everything went well, just add in the following line (including the ";") after the mail($to, $subject, $emailcontent, $from); command.
print "everything went well. email sent.";
I get the "Everything worked" message but I ahve tried loads of times and have recieved no emails. I have tried with 2 different email addresses too.
I changed what you said and this is the code I'm using:

i copied whatever you had in your post and just chaned $to to my own email address... then i loaded it up to my host... and it worked - no problems at all. i dun know why it didn't work for you. can someone else try it out at their server too?
also, if you can try replacing:
1. mail($to, $subject, $emailcontent, $from);
with
2. print $emailcontent;
and try it out. instead of sending an email, the contents of the email will be printed to the screen. if this works, then i suspect something is wrong with your server running the mail command...
But still no emails.
I have no idea what is up....
If it is my server not running the mail command right, what can I do about it?
$to = "cannonballguy@hotmail.com";
$subject = "xxx security code test xxx";
$from = "cannonballguy@hotmail.com";
is cannonballguy@hotmail.com a valid email address? can you try using different values for $to and $from?
I ahve tried other addresses with no luck...
