In what ways can PHP developers encourage self-learning and problem-solving in forum discussions, rather than relying on others to provide complete solutions?

Issue: PHP developers can encourage self-learning and problem-solving in forum discussions by providing guidance and hints rather than giving complete solutions. This approach helps developers think critically and develop their problem-solving skills. Code snippet:

// Example of providing guidance in a forum discussion
// Hint: Use a loop to iterate through the array and check for a specific condition

$numbers = [1, 2, 3, 4, 5];
$target = 3;

foreach ($numbers as $number) {
    if ($number == $target) {
        echo "Target number found!";
        break;
    }
}
