Wouldn't using asort in the above function do what you're asking?

function calculate_average($arr)

The primary reason I used a loop was so you can mess around with each array element; i.e. check with is_numeric or something along those lines.]]> http://www.mdj.us/web-development/php-programming/calculating-the-median-average-values-of-an-array-with-php/#comment-1190 Thu, 24 Jun 2010 22:31:11 +0000
In the calculate_average function, you can replace the foreach loop with this:

$total = array_sum($arr);

They've got min: http://www.php.net/manual/en/function.min.php
and max: http://www.php.net/manual/en/function.max.php

but no avg... go figure.]]> http://www.mdj.us/web-development/php-programming/calculating-the-median-average-values-of-an-array-with-php/#comment-1026 Fri, 26 Mar 2010 05:31:54 +0000
How come php don't have a native avg function while js does?]]>
