How can proper debugging techniques, such as outputting variable values, help identify and resolve issues in PHP scripts?

Proper debugging techniques, such as outputting variable values, can help identify and resolve 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 it. By outputting variable values, developers can track the flow of data and logic in their scripts, making it easier to identify and fix bugs. 

// Example of outputting variable values for debugging
$variable1 = "Hello";
$variable2 = "World";

echo "Variable 1: " . $variable1 . "<br>";
echo "Variable 2: " . $variable2 . "<br>";

// Perform some operations on the variables
$combined = $variable1 . " " . $variable2;
echo "Combined: " . $combined . "<br>";
