MongoGridFS::storeBytes

(PECL mongo >=0.9.2)

MongoGridFS::storeBytesStores 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

Options for the store.

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 MongoCursorException if the "w" option is set and the write fails.

Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$timeout milliseconds to complete. This does not kill the operation on the server, it is a client-side timeout. The operation in MongoCollection::$wtimeout is milliseconds.

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"
}
