What best practices should be followed when using while loops in PHP?

When using while loops in PHP, it is important to ensure that the loop has a clear exit condition to prevent infinite looping. It is also recommended to initialize any variables used in the loop before the loop starts and to update them within the loop as needed. Additionally, it is good practice to keep the loop body concise and avoid unnecessary complexity to improve code readability and maintainability. 

// Example of using a while loop with proper initialization, exit condition, and variable update
$count = 0;

while ($count < 10) {
    echo "Count: " . $count . "\n";
    $count++;
}
