What are some common pitfalls when using LDAP queries in PHP, especially when trying to display the results in a PDF table using FPDF?

Common pitfalls when using LDAP queries in PHP include not properly binding to the LDAP server, not escaping user input to prevent LDAP injection attacks, and not handling errors gracefully. When trying to display LDAP query results in a PDF table using FPDF, make sure to properly format the data before adding it to the PDF table. 

// Example LDAP query and FPDF table display
$ldapServer = "ldap.example.com";
$ldapUsername = "cn=admin,dc=example,dc=com";
$ldapPassword = "password";
$ldapBaseDn = "dc=example,dc=com";

$ldapConn = ldap_connect($ldapServer);
ldap_bind($ldapConn, $ldapUsername, $ldapPassword);

$filter = "(objectClass=*)";
$attributes = array("cn", "mail");
$result = ldap_search($ldapConn, $ldapBaseDn, $filter, $attributes);
$entries = ldap_get_entries($ldapConn, $result);

require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 12);

foreach ($entries as $entry) {
    $cn = $entry['cn'][0];
    $mail = $entry['mail'][0];
    
    // Add data to PDF table
    $pdf->Cell(50, 10, $cn, 1, 0, 'C');
    $pdf->Cell(50, 10, $mail, 1, 1, 'C');
}

$pdf->Output();
