What steps can be taken to debug and troubleshoot PHP scripts that are not functioning as expected, such as only returning an "else" response?

Issue: If a PHP script is only returning an "else" response, it may indicate that the condition in an if-else statement is not being met. To troubleshoot this, check the logic of the condition and the variables being used in the comparison.

php 
// Example PHP code snippet with an if-else statement
$number = 10;

if ($number > 5) {
    echo "Number is greater than 5";
} else {
    echo "Number is not greater than 5";
}
