What potential issues can arise when using the while loop and include function in PHP?

One potential issue that can arise when using a while loop with the include function in PHP is the possibility of an infinite loop if the included file also contains the same while loop. To solve this issue, you can use a flag variable to control the loop and ensure it only runs once. 

$flag = true;
while ($flag) {
    include 'file.php';
    $flag = false;
}
