How can PHP developers handle parsing mathematical expressions with multiple operators and parentheses effectively?

Handling parsing of mathematical expressions with multiple operators and parentheses effectively can be achieved by using the shunting yard algorithm. This algorithm allows for the conversion of infix notation (common mathematical notation) to postfix notation (Reverse Polish Notation), which makes it easier to evaluate the expression. By implementing this algorithm in PHP, developers can effectively handle complex mathematical expressions with multiple operators and parentheses. 

function shuntingYard($expression) {
    // Implement the shunting yard algorithm here
}

$expression = "3 + 4 * ( 2 - 1 ) / 5";
$postfixExpression = shuntingYard($expression);
echo $postfixExpression;
