This works here:
<?php
$history['order_total'] =3D '$241.47';
$number_percent=3D"25";//should be without the quotes indeed, but just t=
o =
show PHP can cast this correctly
echo "history['order_total'] is ".$history['order_total']."<br />";
$removeit=3Dstr_replace('$' ,'', $history['order_total']);
echo "strip the $ sign ".$removeit."<br />";
$total =3D ($removeit * (1+($number_percent/100)));
echo "<br />total is ".$total."<br />";
?>
So I'd say there's something wrong with the exact contents of =
$history['order_total'] in your script.
What if you do this (a bit overkill):
$removeit =3D preg_replace('/[^0-9.]/','',$history['order_total']);
If this doesn't work, I'm very curious what the output of =
floatval($history['order_total'])(or floatval($removeit)) is....
