MongoGridFS::storeBytes

(PECL mongo >=0.9.2)

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

说明

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

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 extra 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"
}
