I probably worded it badly...but I am working on a project and i need to take the number that the user puts in and multiply it by 9.8. (to get the weight of the object)
i want to be able to reference whatever that equals later..so i think this is what i want:
<?php $fgravity = '$_POST["mass"] * 9.8';?>
<?php echo $fgravity;?>
but it doesnt work. It literally echos $_POST["mass"] * 9.8
the "mass" the user inputs on the previous page.
Does anyone know how to make this work?
Thanks!
