I've asked a few people, but I don't know what this is called, so it is kind of hard to search for it. What I want to do, is something like...

Let's say $one is "Roger Man" and $two is "Johnny Boy." I want to make $result "Roger ManJohnny Boy."

Anyone know how to do it in php? While I am at it...

Anyone know how to or what it is called when you make take "1" and make it "01" or "001"? They are all equal to each other mathematically but different as strings. I could do it with an IF ELSEIF thing and the stitching thing if I only knew how. :\

"stitching together stings" is called concatenation

This is the way you can do it in perl:

$result = $one . $two;

Since PHP and perl are much alike, try it, it may work.

There are two way, one is what SR said. Another way is to put it in a string itself. When PHP sees double quotes, it evaluates everything inside the quotes. So you can do:
$result = "$one$two";

Because it evaluates what's in the quotes, you can incorporate variable values into strings. So you can have:
$result = "I saw $one and $two the other day.";
echo $result;

That will print out:
I saw Roger Man and Johnny Boy the other day.

If you use single quotes, it doesn't evaluate it. So if you have the code:
$result = 'I saw $one and $two the other day.';
echo $result;

It will print out:
I saw $one and $two the other day.

So you have an easy way of incorporating variables into strings. The other way is to use SR's way, so it would look like:
$result = "I saw " . $one . " and " . $two . " the other day.";

Either of em works, it's just your personal preference. I mix and match, depends on how I'm using the variables. Sometimes it looks cleaner to use the . method, but sometimes I want to show that the variable value is a central part of the string. Your preference

perg- after reading that I think it should have been obvious.

I can't believe I didn't see it, I've used the same method before but not for what I want to use it for.

Thanks SR and Perg.

yeah, in perl you can do it how pergesu suggested. I just shied away from bunching 2 vars up against each other, so I didn't mention it. It probably is fine though.
