Just a simple function to trim digits from the left side of an integer. TRIM DOWN TO 4-> (ie.
987654 => 7654)
function trimInteger($targetNumber,$newLength) {
$digits = pow(10,$newLength);
$s = ($targetNumber/ $digits); //make the last X digits the decimal part
$t = floor($tradeID / $digits); //drop the last X digits (the decimal part)
$h = $s - $t; //remove all but the decimal part
$newInteger = ($h*$digits); //make the everything after the decimal point the new number
return $newInteger;
}
