Post and Pre Increment in PHP?

<?php

$i = 10;
$a = $i++;

echo $a; // It return original value 10

$i = 10;
$a = ++$i; // It return updated value 11

echo $a;

My question is when to use post and pre increment; I know it is useful for loops, and it increments the value like written in above code, but I am confused whether to use post or pre increment and in which case it most efficient. I also hear that for performance wise, pre-increment is more effective.
