What are common pitfalls to avoid when using loops in PHP arrays?

One common pitfall to avoid when using loops in PHP arrays is modifying the array during iteration, as this can lead to unexpected behavior or errors. To solve this issue, it is recommended to create a copy of the array before iterating over it to avoid any modifications affecting the loop. 

// Create a copy of the array before iterating
$array = [1, 2, 3, 4, 5];
$arrayCopy = $array;

foreach ($arrayCopy as $value) {
    // Perform operations on $value
}
