variables!

[oobradersoo]

if you have 4 variables is there anyway to link them into one variable?

{

$number1

$number2

$number3

$number4

}

$wholenumber

Using arithmetic?

Depends on what you mean by 'link them into one variable'.

//You can add/subtract/divide/multiply them all, as suggested by kadeous
$wholenumber = $number1 + number2 + $number3 + $number4;
$wholenumber = $number1 - number2 - $number3 - $number4;
$wholenumber = $number1 / number2 / $number3 / $number4;
$wholenumber = $number1 * number2 * $number3 * $number4;
 
//You can concatenate them
$wholenumber = $number1 . $number2 . $number3 . $number4
 
//You can put them into an array
$wholenumber = array(
    $number1, $number2, $number3, $number4
);

Those are three very basic things that you could do to 'link' them, which is all we can really suggest without more information as to what you actually want

You can also write

 

$number1 = $number2 = $number3 = $number4;

 

But if you are doing this - why do you even HAVE 4 variables?  Sloppy code work?
