Are there any potential pitfalls to be aware of when iterating through arrays in PHP?

One potential pitfall when iterating through arrays in PHP is modifying the array during the iteration, which can lead to unexpected results or errors. To avoid this issue, it is recommended to make a copy of the array before iterating through it. This can be done using the `foreach` loop to create a copy of the array and then iterate through the copy instead of the original array. 

// Create a copy of the original array
$arrayCopy = $originalArray;

// Iterate through the copy of the array
foreach ($arrayCopy as $value) {
    // Perform operations on $value
}
