php中ldap怎么查询用户和组

在PHP中可以使用LDAP（Lightweight Directory Access Protocol）来查询用户和组。以下是一个简单的示例代码：

连接LDAP服务器：

$ldapServer = 'ldap://ldap.example.com';$ldapPort = 389;$ldapConn = ldap_connect($ldapServer, $ldapPort);

绑定LDAP管理员账号：

$ldapAdmin = 'cn=admin,dc=example,dc=com';$ldapPassword = 'password';ldap_bind($ldapConn, $ldapAdmin, $ldapPassword);

查询用户：

$ldapBaseDn = 'ou=users,dc=example,dc=com';$ldapFilter = '(objectClass=person)';$ldapAttributes = array('cn', 'mail');$ldapSearch = ldap_search($ldapConn, $ldapBaseDn, $ldapFilter, $ldapAttributes);$ldapEntries = ldap_get_entries($ldapConn, $ldapSearch);foreach ($ldapEntries as $entry) {    echo "Username: " . $entry['cn'][0] . ", Email: " . $entry['mail'][0] . "<br>";}

查询组：

$ldapGroupBaseDn = 'ou=groups,dc=example,dc=com';$ldapGroupFilter = '(objectClass=groupOfUniqueNames)';$ldapGroupAttributes = array('cn', 'uniqueMember');$ldapGroupSearch = ldap_search($ldapConn, $ldapGroupBaseDn, $ldapGroupFilter, $ldapGroupAttributes);$ldapGroupEntries = ldap_get_entries($ldapConn, $ldapGroupSearch);foreach ($ldapGroupEntries as $entry) {    echo "Group: " . $entry['cn'][0] . "<br>";    foreach ($entry['uniquemember'] as $member) {        echo "Member: " . $member . "<br>";    }}

请注意，以上代码仅供参考，具体的LDAP服务器配置和数据结构可能会有所不同。在实际应用中，您需要根据您的LDAP服务器的配置和数据结构进行相应的调整。
