How can debugging techniques like var_dump and test outputs help identify errors in PHP scripts?

Debugging techniques like var_dump and test outputs can help identify errors in PHP scripts by allowing developers to inspect the values of variables at different points in the code execution. By using var_dump, developers can print out the contents of a variable to see its data type and value, which can help pinpoint where the issue lies. Test outputs can also be used to print out intermediate results or messages to track the flow of the code and identify any unexpected behaviors. 

// Example code snippet using var_dump and test outputs for debugging
$number1 = 10;
$number2 = 5;

// Using var_dump to inspect the values of variables
var_dump($number1); // Output: int(10)
var_dump($number2); // Output: int(5)

// Performing a test output to track the flow of the code
echo "Adding $number1 and $number2: " . ($number1 + $number2); // Output: Adding 10 and 5: 15
