Best practice when using for sintax

Best way to use for sintax

<?php
 for($i=0;$i<$nr;++$i){ /*code*/ } 
?>

Where $nr is an integer.
Note: ++$i is way better than $i++, the reason is that $i++ creates a variable, while ++$i doesn't. So the speed of the process will be better.

Free memory usage (RAM)

When you're coding please consider the use of ressources, best way to optimize a code is to make sure that there aren't any memory leaks.

Using the command unset($variable,$var2) you can free the memory that is allocated by variable/constats.

I will give a simple example, how to use that function

<?php 
$a="something";$b="2";$c[0]="x"; $c[1]="yes";
//free memory usage
unset($a,$b,$c);
//after you used unset, $a,$b,$c will be NUL
?>

Simple and eficient!
