How can debugging techniques be used to identify and resolve errors in PHP scripts?

To identify and resolve errors in PHP scripts, debugging techniques such as using error reporting, logging, and step-by-step debugging can be utilized. By enabling error reporting, you can see any warnings or errors that may occur during script execution. Logging can help track the flow of the script and pinpoint where issues arise. Step-by-step debugging allows you to pause the script at specific points to inspect variables and expressions.

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Log errors to a file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Step-by-step debugging with breakpoints
// Example using xdebug
xdebug_break();
