What debugging techniques can be used to troubleshoot issues with empty content being displayed in the PDF table generated from LDAP query results in PHP?

Issue: The empty content being displayed in the PDF table generated from LDAP query results in PHP could be due to incorrect data retrieval or parsing errors. To troubleshoot this issue, you can start by checking the LDAP query results to ensure that the data is being fetched correctly. Additionally, verify the data parsing and table generation logic to ensure that the retrieved data is properly formatted and displayed in the PDF table. 

// LDAP query to fetch data
$ldapServer = 'ldap.example.com';
$ldapPort = 389;
$ldapUsername = 'cn=admin,dc=example,dc=com';
$ldapPassword = 'password';
$ldapBaseDn = 'dc=example,dc=com';

$ldapConnection = ldap_connect($ldapServer, $ldapPort);
ldap_bind($ldapConnection, $ldapUsername, $ldapPassword);

$ldapFilter = '(objectClass=*)';
$ldapAttributes = array('cn', 'mail');
$ldapSearch = ldap_search($ldapConnection, $ldapBaseDn, $ldapFilter, $ldapAttributes);
$ldapEntries = ldap_get_entries($ldapConnection, $ldapSearch);

// Check LDAP query results
if ($ldapEntries['count'] > 0) {
    // Loop through LDAP query results and display in PDF table
    foreach ($ldapEntries as $entry) {
        if (isset($entry['cn'][0]) && isset($entry['mail'][0])) {
            // Add data to PDF table
            $pdf->Cell(50, 10, $entry['cn'][0], 1, 0, 'C');
            $pdf->Cell(50, 10, $entry['mail'][0], 1, 1, 'C');
        }
    }
} else {
    echo 'No LDAP query results found.';
}

// Close LDAP connection
ldap_close($ldapConnection);
