MongoGridFS::storeFile
(PECL mongo >=0.9.0)
MongoGridFS::storeFile — Stores a file in the database
说明
$filename
[, array $metadata
= array()
[, array $options
= array()
]] ) : mixed参数
-
filename
-
Name of the file or a readable stream to store.
-
metadata
-
Other metadata fields to include in the file document.
Note:
These fields may also overwrite those that would be created automatically by the driver, as described in the MongoDB core documentation for the » files collection. Some practical use cases for this behavior would be to specify a custom chunkSize or _id for the file.
options
An array of options for the insert operations executed against the chunks and files collections. See MongoCollection::insert() for documentation on these these options.
返回值
Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the extra
parameter.
错误/异常
Throws MongoGridFSException if there is an error
reading filename
or inserting into the
chunks or files collections.
范例
Example #1 MongoGridFS::storeFile() with additional metadata
<?php
$m = new MongoClient();
$gridfs = $m->selectDB('test')->getGridFS();
$id = $gridfs->storeFile('example.txt', array('contentType' => 'plain/text'));
$gridfsFile = $gridfs->get($id);
var_dump($gridfsFile->file);
?>
以上例程的输出类似于:
array(7) { ["_id"]=> object(MongoId)#6 (0) { } ["contentType"]=> string(10) "plain/text" ["filename"]=> string(11) "example.txt" ["uploadDate"]=> object(MongoDate)#7 (0) { } ["length"]=> int(26) ["chunkSize"]=> int(262144) ["md5"]=> string(32) "c3fcd3d76192e4007dfb496cca67e13b" }
