How can the script be debugged to determine if it is reaching the elseif branch and why the redirection is not happening as intended?

To debug the script and determine if it is reaching the elseif branch, you can add some debugging statements like echo or var_dump within the branches to see which one is being executed. Additionally, check if the conditions in the elseif statement are being met correctly. To address the redirection issue, make sure that the header() function is called before any output is sent to the browser. 

<?php
if (condition1) {
    // code block
} elseif (condition2) {
    // code block
    header("Location: https://example.com/newpage.php");
    exit();
} else {
    // code block
}
?>
