What are some common pitfalls when using integer variables in PHP loops?

Common pitfalls when using integer variables in PHP loops include not properly initializing the variable before the loop, not updating the variable within the loop, and not defining the loop termination condition correctly. To avoid these pitfalls, make sure to initialize the variable with a value before the loop, update the variable within the loop to control the loop iteration, and define the loop termination condition based on the variable's value. 

// Initializing the variable before the loop
$counter = 0;

// Loop with correct initialization, update, and termination condition
while ($counter < 10) {
    // Loop body
    echo $counter . "<br>";
    
    // Update the variable within the loop
    $counter++;
}
