I have an application that allows the users to input a formula:
(Width*Height)/144
This formula gets updated with a part's specific width & height and
actually returns:
(36.00000*58.00000)/144
I use preg_replace to replace Width and Height with values from the
following array:
[Width] => 36.00000
[Height] => 58.00000
How can I get the resulting formula to actually calculate?
Simplified version of my code:
$partFormula = '(Width*Height)/144';
$prof = array('Width'=>36,'Height'=>58);
$find = array();
$replace = array();
foreach($prof AS $key => $val){
array_push($find,"[$key]");
array_push($replace,$val);
}
return preg_replace($find,$replace,$partFormula);
//returns (36.00000*58.00000)/144
eval() doesn't seem to do much for me (parse error, unexpected $end).

Try;
$foo = preg_replace($find,$replace,$partFormula);
return $foo
