How can test outputs be effectively used to troubleshoot PHP code like the one provided?

Issue: The provided PHP code snippet is not outputting the expected result due to a syntax error in the if statement. To troubleshoot this, we can use test outputs to identify where the issue lies and correct it. 

// Incorrect code snippet
$num = 10;

if ($num == 10) {
    echo "Number is equal to 10";
} else {
    echo "Number is not equal to 10";
}
```

To effectively use test outputs to troubleshoot this PHP code, we can add `var_dump($num);` before the if statement to check the value of `$num` and ensure it is set correctly. Additionally, we can add `echo "Test";` inside the if and else blocks to see if the code execution reaches those points.

```php
$num = 10;

var_dump($num);

if ($num == 10) {
    echo "Number is equal to 10";
} else {
    echo "Number is not equal to 10";
}
