This functions seems so powerful... just when i saw it i thought about writing a fast average of n numbers function so here it is, it is very simple... example usage included.
<?php
//Calculate the average of the numbers given
function avg(){
$sum = 0;
for($i = 0; $i < func_num_args(); $i++){
$sum += func_get_arg($i);
}
$avg = $sum / func_num_args();
return $avg;
}
echo sprintf("%.2f",avg(2,1,2,1,3,4,5,1,3,6));
?>
