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

Debugging techniques such as using print statements, var_dump, or step-through debugging can help identify where errors are occurring in PHP code. By examining the output or the values of variables at different points in the code, developers can pinpoint the source of the issue and make necessary corrections. 

// Example PHP code snippet with debugging techniques
$variable1 = 10;
$variable2 = 20;

// Using var_dump to inspect variables
var_dump($variable1, $variable2);

// Adding a print statement to track the flow of the code
echo "Before calculation: variable1 = $variable1, variable2 = $variable2";

// Performing some calculations
$result = $variable1 + $variable2;

// Using var_dump again to check the result
var_dump($result);

// Adding another print statement to track the flow of the code
echo "After calculation: result = $result";
