# ldap_count_entries

(PHP 4, PHP 5, PHP 7, PHP 8)

ldap_count_entries — Count the number of entries in a search

### 说明

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 number of entries in the result, 或者在失败时返回 `false`.

### 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)
