How does this code block works?
- by Justin John
I can't understand how the following code works.
$start = 1;
while($start<10){
if ($start&1) {
echo "ODD ".$start." <br/> ";
}
else {
echo "EVEN ".$start." <br/> ";
}
$start++;
}
The $start&1 will return ODD and EVEN seperately.
Output
ODD 1
EVEN 2
ODD 3
EVEN 4
ODD 5
EVEN 6
ODD 7
EVEN 8
ODD 9
If we give $start&2 instead of $start&1, it returns with another order.
How &1 &2 etc... works here?
