How can one troubleshoot and debug PHP code to identify issues like empty arrays?

To troubleshoot and debug PHP code to identify issues like empty arrays, one can use functions like var_dump() or print_r() to inspect the contents of the array and check if it is empty. Additionally, using conditional statements like empty() or count() can help determine if the array is empty. By carefully examining the code and using these debugging techniques, one can pinpoint the issue and resolve it effectively. 

$array = []; // Define an empty array

// Check if the array is empty using empty() function
if (empty($array)) {
    echo "Array is empty";
} else {
    echo "Array is not empty";
}
