How can PHP developers effectively troubleshoot and debug issues related to array manipulation in their code?

To effectively troubleshoot and debug issues related to array manipulation in PHP code, developers can use functions like var_dump() or print_r() to inspect the contents of arrays at different stages of the code execution. They can also use error reporting functions like error_log() to log any errors or warnings related to array manipulation. Additionally, using step-by-step debugging tools like Xdebug can help identify and fix issues in array manipulation code.

// Example code snippet demonstrating how to debug array manipulation issues
$array = [1, 2, 3, 4, 5];

// Inspect the contents of the array
var_dump($array);

// Perform array manipulation operations
$array[] = 6;
unset($array[2]);

// Check the modified array
var_dump($array);
