How can one troubleshoot and resolve errors related to foreach loops in PHP when filling arrays?

When encountering errors with foreach loops in PHP when filling arrays, it is important to ensure that the variable being iterated over is indeed an array. Additionally, double-check the array key-value pairs to avoid any unexpected behavior. Finally, consider using the empty() function to verify if the array is empty before attempting to iterate over it. 

// Example code snippet to troubleshoot and resolve errors related to foreach loops in PHP when filling arrays

// Initialize an empty array
$myArray = [];

// Check if the array is empty before using foreach loop
if (!empty($myArray)) {
    // Iterate over the array using foreach loop
    foreach ($myArray as $key => $value) {
        // Process each key-value pair
        echo "Key: $key, Value: $value <br>";
    }
} else {
    echo "Array is empty.";
}
