functions and returning values

[bakaneko]

hi,

how do you return values in functions so that if there are two possible values each one can be returned rather than the last one. i have a function that returns either 1 for true and 0 for false. but it always returns false because i dont think it ends when it is true:

function check_dupes ($var1, $var2) {

while (blah) {

if (blah?) {
return 1;
}
}
return 0;

}

there is another way of doing this using an if/else at the end, but i would like to know what i am doing wrong here.

thanks,

bakaneko

I think I would actually have to see what you're replacing with "blah" to understand why it doesn't work. Because, if your while and if statements do work correctly, I don't see why that shouldn't work.

a given function can only return one value.

Of couse this doesnt have to be a scalar value, e.g. you could return an array in PHP.
Another method of getting the function to "return" more than one value is to pass a parameter by reference and then check its value in the main script.
