MongoGridFS::storeBytes — Stores a string of bytes in the database
$bytes
[, array $metadata = array()
[, array $options = array()
]] )
bytes
String of bytes to store.
metadata
Other metadata fields to include in the file document.
Note:
These fields may also overwrite those that would be created automatically by the driver, as described in the MongoDB core documentation for the » files collection. Some practical use cases for this behavior would be to specify a custom chunkSize or _id for the file.
options
Options for the store.
"w"
See WriteConcerns. The default value for MongoClient is 1.
Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the extra parameter.
Throws MongoCursorException if the "w" option is set and the write fails.
Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$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.
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"
}
