What does this do in a for loop?
$counter+=1
it's shorthand for $counter = $counter + 1;
which in this case (because 1 is being added)
can also be written as:
$counter++;
or
++$counter;
those last 2 alternatives give the same result
but they are _not_ exactly equivalent - it has to do
with when the incrementation is done when such expression
appears inside a more complex expression e.g.
$counter = 1;
$x = ++$counter;
$counter = 1;
$y = $counter++;
echo $x,",",$y,"\n"; // outputs: 2,1
