Are there any specific debugging techniques or functions in PHP that can help identify and resolve issues with incomplete output or missing data?

Issue: Incomplete output or missing data in PHP can be caused by errors in the code such as syntax errors, logic errors, or issues with data retrieval. To identify and resolve these issues, debugging techniques like using var_dump() or print_r() to display variable values, checking error logs for any PHP errors, and using step-by-step debugging tools like Xdebug can be helpful. 

// Example PHP code snippet using var_dump() to debug missing data
$data = ['apple', 'banana', 'cherry'];

// Check if data is missing
var_dump($data);
