In what ways can the user improve their understanding of PHP and programming concepts to troubleshoot and resolve issues like the visitor counter not incrementing correctly?

Issue: The visitor counter is not incrementing correctly because the code logic for updating the counter is incorrect. To fix this issue, we need to ensure that the counter variable is being properly incremented each time a visitor accesses the page. 

// Current incorrect code logic for updating the visitor counter
$counter = 0; // Initialize the counter variable
$counter++; // Increment the counter by 1
echo "Visitor Count: " . $counter; // Display the updated visitor count

// Corrected code logic for updating the visitor counter
$counter = 0; // Initialize the counter variable
$counter = $counter + 1; // Increment the counter by 1
echo "Visitor Count: " . $counter; // Display the updated visitor count
