How can debugging techniques help identify and resolve PHP code errors?

Debugging techniques, such as using var_dump(), print_r(), or error reporting, can help identify and resolve PHP code errors by providing insights into variables' values, function outputs, and error messages. By systematically analyzing the output of these debugging tools, developers can pinpoint the exact location and nature of the error, allowing them to make necessary corrections and improvements to the code.

// Example code snippet demonstrating the use of var_dump() to identify and resolve PHP code errors
$number = 10;
$string = "Hello";
$result = $number + $string; // This line will produce a PHP error

var_dump($result); // Output the variable $result to identify the error
