Shorten large numbers into abbreviations (i.e. 1,500 = 1.5k)

numberAbbreviation.php

<?php
/**
 * Shorten large numbers into abbreviations (i.e. 1,500 = 1.5k)
 *
 * @param int    $number  Number to shorten
 * @return String   A number with a symbol
 */ 
function numberAbbreviation($number) {
    $abbrevs = array(12 => "T", 9 => "B", 6 => "M", 3 => "K", 0 => "");

    foreach($abbrevs as $exponent => $abbrev) {
        if($number >= pow(10, $exponent)) {
        	$display_num = $number / pow(10, $exponent);
        	$decimals = ($exponent >= 3 && round($display_num) < 100) ? 1 : 0;
            return number_format($display_num,$decimals) . $abbrev;
        }
    }
}
?>

When the $number is 0, this returns empty.

I added 'return $number;' as the last line of the function to solve the 0 issue.

seems to work good, thank you sir, you are a gentleman and a scholar
