1.2.822. No Plus One

Incrementing a variable should be done with the ++ or – operators. Any other way, may be avoided.

This is a micro optimisation.

<?php

// Best way to increment
++$x; --$y;

// Second best way to increment, if the current value is needed :
echo $x++, $y--;

// Good but slow
$x += 1;
$x -= -1;

$y += -1;
$y -= 1;

// even slower
$x = $x + 1;
$y = $y - 1;

?>
