How can debugging techniques, such as outputting variable values, help in identifying and resolving issues in PHP scripts?

Debugging techniques like outputting variable values can help in identifying and resolving issues in PHP scripts by allowing developers to see the actual values of variables at different points in the code execution. This can help pinpoint where the issue is occurring and what values are causing the problem. By outputting variable values, developers can track the flow of data through the script and identify any unexpected or incorrect values that may be causing errors. 

// Example PHP code snippet demonstrating how outputting variable values can help in debugging

$number1 = 10;
$number2 = 5;

$result = $number1 + $number2;

echo "Number 1: " . $number1 . "<br>";
echo "Number 2: " . $number2 . "<br>";
echo "Result: " . $result . "<br>";
