pasting bits of numbers together in php

[malcolmcroucher]

I have several numbers i would like to put together to form a bigger number ? how does it work ?

e.g

$num = 123 ;
$num2 = 234 ;
$num3 = 345 ;

i would like to do a long number = 123234345 ?

regards

Malcolm

$bignum = $num . $num2 . $num3;
