How can you create a function that returns true 1/100 of the time?

anyone know?

function make_seed() {
    list($usec, $sec) = explode(' ', microtime());
    return (float) $sec + ((float) $usec * 100000);
}
srand(make_seed());
$randval = rand();

function oneinahundred(){
        if (rand(0,99)<1) return TRUE;
        else return FALSE;
}

for ($i=0;$i<1000;$i++){
        if (oneinahundred()) print "1";
        else print "0";
}

do you mean every 100th time? If so, how about using the modulus operator?
