How can the code be optimized to handle empty text field values more effectively when using ldap_mod_replace?

When using ldap_mod_replace to update LDAP attributes, empty text field values can cause issues. To handle empty values effectively, you can check if the field is empty before attempting to replace it with ldap_mod_replace. If the field is empty, you can either skip the update or delete the attribute from the LDAP entry.

// Check if the field is empty before using ldap_mod_replace
if (!empty($fieldValue)) {
    $replace = ldap_mod_replace($ldapConnection, $dn, array($attribute => $fieldValue));
} else {
    // If field is empty, you can choose to skip the update or delete the attribute
    // Skip update
    // $replace = true;
    
    // Delete attribute
    $delete = ldap_mod_del($ldapConnection, $dn, array($attribute => array()));
}
