What role does the `error_reporting(-1);` function play in debugging PHP code, and how can it help in resolving issues with array manipulation?

The `error_reporting(-1);` function in PHP sets the error reporting level to report all errors. This can be helpful in debugging PHP code as it allows you to see all errors, warnings, and notices that may be occurring. When dealing with array manipulation, setting the error reporting level to report all errors can help in identifying any issues with array functions or operations, such as accessing undefined indexes or trying to manipulate arrays in unexpected ways.
