I have foreach loop in which I need to assign coordinates after certain steps. For this example $n+4 (174,178,182,...).
I know that solve multiple entering n++.
$n = 174;
foreach($items as $item){
echo $item . ' coor: ' . $n . '<br>';
$n++;
$n++;
$n++;
$n++;
}
I wonder if it can not be solved more elegantly.
You can use:
$n += 4;
When you put an operator before =, it creates an operator that combines the original value of the target with the source using that operation, so that's equivalent to:
$n = $n + 4;
Similarly, if you write:
$n *= 10;
it's the same as
$n = $n * 10;
@Barmar 's solution and explanation is correct and solves your issue. But here is an alternative way you could write that code which you may find helpful:
$n = 174;
foreach($items as $i => $item){
echo $item . ' coor: ' . $n + $i*4 . '<br>';
}
Note this will only work if your array keys are numeric and incrementing. If they're not then you just need to change $items in the foreach to array_values($items).
