Hi guys - thanks SO much for your replies - it is still not working -
I'm using the floatval properly but it is returning a zero :
Input :
echo "history['order_total'] is ".$history['order_total']."<br />";
$removeit=str_replace('$' ,'', $history['order_total']);
echo $removeit;
$floatandremove = floatval($removeit);
echo "<br />floatandremove is ".$floatandremove;
exit;
Output :
history['order_total'] is $241.47
241.47
floatandremove is 0
This is getting crazy!
