MongoGridFS::storeBytes — Stores a string of bytes in the database

说明

public MongoGridFS::storeBytes ( string $bytes [, array $metadata = array() [, array $options = array() ]] ) : mixed

参数

bytes

String of bytes 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 metadata parameter.

错误／异常

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

范例

Example #1 MongoGridFS::storeBytes() with additional metadata

<?php$m = new MongoClient();$gridfs = $m->selectDB('test')->getGridFS();$bytes = 'abcdefghijklmnopqrstuvwxyz';$id = $gridfs->storeBytes($bytes, array('_id' => 'alphabet'));$gridfsFile = $gridfs->get($id);var_dump($gridfsFile->file);?>

以上例程的输出类似于：

array(7) {
  ["_id"]=>
  string(8) "alphabet"
  ["uploadDate"]=>
  object(MongoDate)#7 (0) {
  }
  ["length"]=>
  int(26)
  ["chunkSize"]=>
  int(262144)
  ["md5"]=>
  string(32) "c3fcd3d76192e4007dfb496cca67e13b"
}
