How should the comparison operator be used in a while loop when checking for false in PHP code?

When using the comparison operator in a while loop to check for false in PHP, it is important to ensure that the condition being checked evaluates to false to exit the loop. This can be achieved by using the comparison operator `!==` to explicitly check for false, as the regular `!=` operator may consider other values like null, 0, or an empty string as equivalent to false. 

// Example of using the comparison operator !== in a while loop to check for false
$condition = true;

while ($condition !== false) {
    // Code inside the loop
    
    // Update the condition if needed
    $condition = false; // This will eventually make the loop exit
}
