What are the best practices for debugging PHP code to identify array-related errors?

When debugging PHP code to identify array-related errors, it is important to first check if the array is properly initialized and populated with the expected data. Use functions like var_dump() or print_r() to display the array structure and values for easier inspection. Additionally, make sure to check for typos in array keys and indexes, as well as proper usage of array functions like array_push(), array_pop(), etc.

// Example code snippet for debugging array-related errors
$array = [1, 2, 3, 4, 5]; // Initialize an array

// Display array structure and values for inspection
var_dump($array);

// Check for typos in array keys and indexes
echo $array[3]; // Output: 4

// Use array functions properly
array_push($array, 6); // Add element to the end of the array
print_r($array); // Output: [1, 2, 3, 4, 5, 6]
