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
