I am tring to output 3 different random numbers between 1
and 20 into 3 different strings. Using Rand() for each
string isn't sufficient as I may get the same number
repeated for one of the other strings- eg 1,1,3 or 5,3,3 .
It's important that I get three different numbers outputted
into for
Before you add a number to a string make sure that the number is not in
any of the other ones if they exist.
Use a do-while loop on it...
$one = rand( 1,20 );
do {
$two = rand( 1, 20 );
}while( $two == $one );
do {
$three = rand( 1, 20 );
}while( ($three == $one) ($three == $two) );
echo

Dont you mean || at the last loop? You loop as long as 3 is equal to both 1
and 2, || would cause it to loop while it's equal to any of them..
