What are the best practices for handling LDAP connections in PHP scripts for interacting with Active Directory on a Windows Server?

When handling LDAP connections in PHP scripts to interact with Active Directory on a Windows Server, it is important to securely bind to the LDAP server, perform necessary operations, and properly close the connection to release resources. It is recommended to use secure connections (LDAPS) and bind with a service account that has appropriate permissions to access Active Directory. 

<?php
$ldapServer = 'ldaps://your_ldap_server';
$ldapPort = 636;
$ldapUser = 'your_service_account';
$ldapPass = 'your_password';

$ldapConn = ldap_connect($ldapServer, $ldapPort);
ldap_set_option($ldapConn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldapConn, LDAP_OPT_REFERRALS, 0);

if ($ldapConn) {
    $ldapBind = ldap_bind($ldapConn, $ldapUser, $ldapPass);
    
    // Perform LDAP operations here
    
    ldap_close($ldapConn);
} else {
    echo "Failed to connect to LDAP server";
}
?>
