Fixed matheval function when percentage is less than 10:
<?php
function matheval($equation)
{
$equation = preg_replace("/[^0-9+\-.*\/()%]/","",$equation);
// fix percentage calcul when percentage value < 10
$equation = preg_replace("/([+-])([0-9]{1})(%)/","*(1\$1.0\$2)",$equation);
// calc percentage
$equation = preg_replace("/([+-])([0-9]+)(%)/","*(1\$1.\$2)",$equation);
// you could use str_replace on this next line
// if you really, really want to fine-tune this equation
$equation = preg_replace("/([0-9]+)(%)/",".\$1",$equation);
if ( $equation == "" )
{
$return = 0;
}
else
{
eval("\$return=" . $equation . ";" );
}
return $return;
}
?>
