What best practices should be followed when using foreach loops with PHP arrays?

When using foreach loops with PHP arrays, it is important to check if the array is not empty before iterating over it to avoid errors. Additionally, it is recommended to use the key => value syntax to access both the key and value of each element in the array. Finally, consider using the continue keyword to skip to the next iteration if needed. 

// Check if the array is not empty before iterating over it
if (!empty($array)) {
    // Use the key => value syntax to access both key and value
    foreach ($array as $key => $value) {
        // Code block to process each element in the array
    }
}
