What are alternative approaches to using eval() for evaluating mathematical expressions in PHP?

Using eval() to evaluate mathematical expressions in PHP can be risky as it allows for arbitrary code execution. An alternative approach is to use the built-in PHP functions like `eval()` or `bcmath()` to safely evaluate mathematical expressions. This helps prevent code injection vulnerabilities in your application. 

// Using bcmath() to evaluate mathematical expressions
$expression = "2 + 2 * 3";
$result = bcadd("0", $expression, 8);
echo $result;
