ldap_count_entries — Count the number of entries in a search

### 说明

function ldap_count_entries(LDAP\Connection `$ldap`, LDAP\Result `$result`): int

Returns the number of entries stored in the result of previous search operations.

### 参数

`ldap`

  通过 ldap_connect() 返回的 LDAP\Connection 实例。

`result`

  通过 ldap_list() 或者 ldap_search() 返回的 LDAP\Result 实例。

### 返回值

Returns the number of entries in the result, or `-1` on error.

### 更新日志

版本 | 说明
--- | ---
8.1.0 | 现在 `ldap` 参数接受 LDAP\Connection 实例，之前接受有效的 `ldap link` resource。
8.1.0 | The `result` parameter expects an LDAP\Result instance now; previously, a valid `ldap result` resource was expected.

### 示例

示例 #1 ldap_count_entries() example

Retrieve number of entries in the result.

    // $ds is a valid LDAP\Connection instance for a directory server

         $dn        = 'ou=example,dc=org';
         $filter    = '(|(sn=Doe*)(givenname=John*))';
         $justthese = array('ou', 'sn', 'givenname', 'mail');

         $sr = ldap_search($ds, $dn, $filter, $justthese);

         var_dump(ldap_count_entries($ds, $sr));

以上示例的输出类似于：

    int(1)
