Consider the following:
function test() {
static $i = 0;
$i++;
$retval = ( $i <= 10 ) ? $i : '';
return $retval;
}
while( $bob = test()) {
echo $bob . '<br>';
}
while(false !== ($bob = test())) {
echo $bob . '<br>';
}
You would expect the while loop to go on forever just looking
at the above code. However, what's happening is that when the
empty string is getting returned due to $i being > 10, the while
loop is resolving FALSE when $bob is set to the value of the
empty string.
Is there any way that I can force this not to happen? That the
while loop resolves as FALSE only when the function actually
returns a (boolean) FALSE value?
thnx,
