What role does a check value play in preventing script loops in PHP?

A check value in PHP can prevent script loops by keeping track of whether a certain condition has been met before executing a block of code. By checking the value before entering the loop, we can avoid running the same code multiple times unnecessarily. 

$checkValue = false;

if (!$checkValue) {
    // Run the code block only if the check value is false
    // This prevents the script from entering a loop
    $checkValue = true;
}
