# Formula1
|
|
##Simple Mathematical formulas evaluator for PHP
|
|
|
|
If you need to evaluate a formula with basic operators and variables, and
|
|
|
|
* You dont want to use EVAL for obvious security reasons,
|
|
* You don't want to rely on half the internet as dependancies, but prefer a single self-contained class,
|
|
* You don't necessarily have the latest PHP version,
|
|
* You want something readable that you could easily understand and customize,
|
|
|
|
Then you might like Formula1 ! ;-)

**Simple usage no variables**
|
|
|
|
> $f1 = new Formula1('-45+(41*2)-(6/(3+1))');
|
|
> echo($f1->compute()); // 35.5
|
|

|
**Simple usage with variables**
|
|
|
|
> $f1 = new Formula1('-45+(fourty_one*2)-(6/(three+1))' , ['fourty_one'=>41, 'three'=>3]);
|
|
> echo($f1->compute());
|
|
|
|
|
|
**Funky usage with variables that include formulas themselves (and recusrively)**
|
|
|
|
> $f1 = new Formula1('-45+(fourty_one*2)-(6/(three+1))' , ['fourty_one'=>'82/2', 'three'=>'12/four', 'four'=>4]);
|
|
> echo($f1->compute());
