Using the value of a function

[mdj]

Hi All,

Fairly new to PHP but enjoying the learning!!

Im have a question,

I've generated a random 3 digit number using the following

function makeRandomCode() {
srand((double)microtime()*1000000);
rand(0,100);
}

Im trying to add the generated output to a database, i tried using the following but to no luck.

$randc = makeRandomCode();

Could someone please poin me in the right direction.

well, it has no return value, so it returns nothing, and nothing would be assigned to your variable.

function makeRandomCode() { 
    srand((double)microtime()*1000000); 
    return rand(0,100); 
} 

$randc = makeRandomCode(); 

hope this helps,
xblue

btw. 3 digit number? ~1:100 probability to get a 3 digit number I think 😉
