# SolrClient::addDocuments

(PECL solr >= 0.9.2)

SolrClient::addDocuments — Adds a collection of SolrInputDocument instances to the index

### 说明

public SolrClient::addDocuments(array `$docs`, bool `$overwrite` = `true`, int `$commitWithin` = 0): void

Adds a collection of documents to the index.

### 参数

`docs`

  An array containing the collection of SolrInputDocument instances. This array must be an actual variable.

`overwrite`

  Whether to overwrite existing documents or not. If `false` there will be duplicates (several documents with the same ID).

  警告

  PECL Solr < 2.0 $allowDups was used instead of $overwrite, which does the same functionality with exact opposite bool flag.

  $allowDups = false is the same as $overwrite = true

`commitWithin`

  Number of milliseconds within which to auto commit this document. Available since Solr 1.4 . Default (0) means disabled.

  When this value specified, it leaves the control of when to do the commit to Solr itself, optimizing number of commits to a minimum while still fulfilling the update latency requirements, and Solr will automatically do a commit when the oldest add in the buffer is due.

### 返回值

Returns a SolrUpdateResponse object or throws an exception on failure.

### 错误／异常

Throws SolrClientException if the client had failed, or there was a connection issue.

Throws SolrServerException if the Solr Server had failed to process the request.

### 示例

示例 #1 SolrClient::addDocuments() example

`<?php
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$doc = new SolrInputDocument();
$doc->addField('id', 334455);
$doc->addField('cat', 'Software');
$doc->addField('cat', 'Lucene');
$doc2 = clone $doc;
$doc2->deleteField('id');
$doc2->addField('id', 334456);
$docs = array($doc, $doc2);
$updateResponse = $client->addDocuments($docs);
// no changes will be written to disk unless $commitWithin is passed or SolrClient::commit is called
print_r($updateResponse->getResponse());
?>`

以上示例的输出类似于：

    SolrObject Object
    (
        [responseHeader] => SolrObject Object
            (
                [status] => 0
                [QTime] => 2
            )

    )
