PHP-Handbuch: Stores a file in the database

Beschreibung

public mixed MongoGridFS::storeFile ( string|resource $filename [, array $metadata = array() [, array $options = array() ]] )

Parameter-Liste

filename: Name of the file or a readable stream to store.
metadata: Other metadata fields to include in the file document.

Hinweis:
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.

Rückgabewerte

Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the metadata parameter.

Fehler/Exceptions

Throws MongoGridFSException if there is an error reading filename or inserting into the chunks or files collections.

Beispiele

Beispiel #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);
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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"
}
