What debugging techniques can be used to identify and resolve errors in PHP code?

One common debugging technique in PHP is using error reporting to display any errors or warnings that may occur during code execution. This can be done by setting the error_reporting level in the PHP configuration file or using the error_reporting() function in the code itself. Another technique is to use print_r() or var_dump() functions to output the values of variables at various points in the code to identify any unexpected values. Additionally, using a debugger tool like Xdebug can help step through the code line by line and track variable values. 

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

// Output variable values for debugging
$variable = "Hello";
var_dump($variable);

// Using Xdebug for debugging
// Install Xdebug extension and configure IDE for debugging
// Set breakpoints in the code and step through the code execution
