symfony/expression-language v7.0.3

The Symfony/ExpressionLanguage package is a powerful tool, provided by the Symfony PHP framework, that enables the compilation and evaluation of expressions. Primarily utilized for Boolean evaluations, the ExpressionLanguage component allows developers to encapsulate complex logic within simplistic one-liner expressions, thereby boosting the performance and readability of code.

Utilizing the symfony/expression-language package is relatively straightforward. First, you'll need to include it in your project using Composer with the command: composer require symfony/expression-language.

After the installation, you can use the expression language component as follows:

use Symfony\Component\ExpressionLanguage\ExpressionLanguage;

$expressionLanguage = new ExpressionLanguage();

// The evaluate() method compiles and evaluates the expression
$result = $expressionLanguage->evaluate('1 + 1');

echo $result; // prints 2

In the above code, an instance of the ExpressionLanguage class is created. The evaluate() method is subsequently used to compile and evaluate an expression, with the result outputted to the screen.
