is this possible?

[mga_ka_php]

define('ORIGINAL_PRICE', 49.97);

$computation = "ORIGINAL_PRICE - (ORIGINAL_PRICE * 0.50)";

echo (int) $computation;

 

that code is not working but is that possible or how to code that to work?

Perhaps something like this, if it's just simple maths you're trying to achieve?

 

<?php

$orig = 49.97;

$computation = ($orig - ($orig * 0.50));

echo $computation;

?>

[mga_ka_php]

the reason why my i did that code because the computation will be coming from database and i don't know how to use the computation after i get it from the database. got the idea?

[mga_ka_php]

how do you compute an equation inside a variable?

 

$row['equation'] - from database. example content: ORIGINAL_PRICE - (ORIGINAL_PRICE * 0.50)

 

example

define('ORIGINAL_PRICE', 49.97);
$value = $row['equation'];

 

is it possible?

This is what you need:

http://php.net/manual/en/function.eval.php

 

Store the equation in database as: $ORIGINAL_PRICE - ($ORIGINAL_PRICE * 0.50)

After that, you can do:

$value = eval($row['equation']);
