I have an HTML form file and a PHP file that are supposed to interact with eachother to save information from the form to a contactlist text file. I had it working fine and it has been turned it, but started playing with it and now have a question.
Is it possible to assign more than one form element to one php variable? I want my form to have a specific text field for the area code, the prefix and the line number and then want to combine those three field into one variable. This is not a requirement for my class, I'm just wanting to see how much I can do with this. Here is my html code below:

Answer Wiki:
Yes, you can do this many ways, here is my favorite:
according to your html file, the POST variables will include
$_POST['AreaCode']
$_POST['Prefix']
$_POST['LineNum']
Change your line
"$PhoneNum = ($_POST['Prefix']['LineNumb']);"
to:
$PhoneNum=$_POST['Prefix']."-".$_POST['LineNum'];
So that is using the concat function of php (for combining strings).
In this example we turn
503
555
1234
into
$AreaCode=503
$PhoneNum="555-1234"
If you do not want the hyphen (so you can store as an integer):
$PhoneNum=intval($_POST['Prefix'].$_POST['LineNum']);
Happy coding
