What steps can be taken to troubleshoot issues with PHP redirects not functioning as expected?

Issue: If PHP redirects are not functioning as expected, it could be due to incorrect headers being sent or output being generated before the redirect header. To solve this, ensure that no output is sent before the header() function is called and that the header is formatted correctly.

ob_start(); // Start output buffering

// Perform any necessary checks or logic here

if ($condition) {
    header("Location: new_page.php"); // Redirect to new page
    exit(); // Ensure no further code is executed
}

ob_end_flush(); // Flush output buffer
