How does understanding operator associativity in PHP help in writing more efficient and reliable code?

Understanding operator associativity in PHP helps in writing more efficient and reliable code by ensuring that operators are evaluated in the correct order. This knowledge helps prevent unexpected behavior and errors in expressions. By explicitly specifying the order of operations using parentheses, developers can make their code more readable and maintainable. 

// Example of using parentheses to explicitly specify operator associativity
$a = 5;
$b = 10;
$c = 2;

$result = ($a + $b) * $c; // This ensures addition is performed before multiplication
echo $result; // Output: 30
