How can PHP be utilized to parse and evaluate mathematical expressions containing parentheses and other complex operators?

To parse and evaluate mathematical expressions containing parentheses and other complex operators in PHP, you can utilize the eval() function along with proper error handling to safely evaluate the expression. This approach allows you to evaluate complex mathematical expressions dynamically at runtime. 

<?php
$expression = "(3 + 5) * 2 / (10 - 4)";
$eval_result = @eval("return $expression;");

if ($eval_result === false) {
    echo "Error evaluating expression";
} else {
    echo "Result: " . $eval_result;
}
?>
