Take the 2-minute tour ×  I'm creating a php script which
creates a random number which is 7 digits long and doesn't
contain 0's, the only problem with this is that I have to call
the function rand 7 times and store every number generated in a
different variable, but I was wondering how I could put these
numbers together in a variable instead of adding them together
something along the lines of  $security_number = $1&&$2&&$3 and
so on.  thanks in advance.  share|improve this question string

what you are trying to achieve. You need the mindset that you
actually want a seven character string of digits. For example,
if your number was 0028172, if it is stored as a number then
just like a digital calculator it will be displayed as 28172
unless you use string formatting.  If you already have code
creating the individual digits, simply use concatenation:
$securitycode = $digit1 . $digit2 . $d
