A basic but robust introductory level example of a custom made function that evaluates to an absolute value, mimicing the abs() predefined function. 
Sorry I don't do comments...

<?php

	function abs_mimic($eval) {
	
	if ($eval >= 0) {
	
	$var = $eval; }
	
	else {
	
	$var = -$eval; }
	
	echo $var;
	
	}
	
?>

<?php

	$n1 = 1;
	$n2 = -1;
	
	echo abs($n1*$n2);
	echo abs_mimic($n1*$n2);

?>
