How can PHP developers effectively debug and troubleshoot issues like "Skipping numeric key" errors?

Issue: "Skipping numeric key" errors occur when trying to assign values to an array using numeric keys, which are automatically converted to integers in PHP. To fix this issue, use string keys instead of numeric keys when assigning values to an array. 

// Incorrect way of assigning values with numeric keys
$array = [];
$array[0] = 'value1';
$array[1] = 'value2';

// Correct way of assigning values with string keys
$array = [];
$array['key1'] = 'value1';
$array['key2'] = 'value2';
