In PHP, what is the significance of using parentheses in loops and conditionals?

Using parentheses in loops and conditionals in PHP is important because it helps to clearly define the conditions that need to be met for the loop or conditional statement to execute. Without parentheses, the code may not work as expected or may produce errors. It is a best practice to always use parentheses to ensure the code is clear and easy to understand. 

// Example of using parentheses in a loop
for ($i = 0; $i < 10; $i++) {
    // Loop code here
}

// Example of using parentheses in a conditional statement
if ($x == 5) {
    // Conditional code here
}
