What are some best practices for debugging and troubleshooting issues with PHP arrays that seem to be losing data?

Issue: When debugging and troubleshooting PHP arrays that seem to be losing data, it is important to check for any unintentional overwriting of array elements or incorrect usage of array functions that may be causing the data loss. Additionally, ensuring that the array keys are unique and properly defined can help prevent data loss. 

// Example code snippet to prevent data loss in PHP arrays
// Initialize an array with unique keys to prevent data loss
$data = [
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
];

// To add or update an element in the array without losing data
$data['key4'] = 'value4';

// To retrieve and display the array data
print_r($data);
