MongoGridFS::storeBytes — Stores a string of bytes in the database
$bytes
[, array $metadata
= array()
[, array $options
= array()
]] )
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.
Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the extra
parameter.
Throws MongoGridFSException if there is an error inserting into the chunks or files collections.
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" }
