When encountering issues with PHP code output, what steps can be taken to troubleshoot and identify the root cause of the problem, such as inconsistent link display in the array?

Issue: To troubleshoot inconsistent link display in an array, check the array values to ensure they are correctly formatted URLs. If the links are not displaying as expected, verify that the array is being properly looped through and that the link display code is correctly implemented. 

<?php
// Sample array with inconsistent link display
$links = array(
    'Google' => 'https://www.google.com',
    'Stack Overflow' => 'stackoverflow.com',
    'GitHub' => 'https://github.com'
);

// Loop through the array and display the links
foreach ($links as $name => $url) {
    echo "<a href='$url'>$name</a><br>";
}
?>
