MongoGridFS::storeFile — Stores a file in the database
$filename
[, array $metadata = array()
[, array $options = array()
]] ) : mixed
filename
Name of the file or a readable stream 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
reading filename or inserting into the
chunks or files collections.
Example #1 MongoGridFS::storeFile() with additional metadata
<?php
$m = new MongoClient();
$gridfs = $m->selectDB('test')->getGridFS();
$id = $gridfs->storeFile('example.txt', array('contentType' => 'plain/text'));
$gridfsFile = $gridfs->get($id);
var_dump($gridfsFile->file);
?>
以上例程的输出类似于：
array(7) {
["_id"]=>
object(MongoId)#6 (0) {
}
["contentType"]=>
string(10) "plain/text"
["filename"]=>
string(11) "example.txt"
["uploadDate"]=>
object(MongoDate)#7 (0) {
}
["length"]=>
int(26)
["chunkSize"]=>
int(262144)
["md5"]=>
string(32) "c3fcd3d76192e4007dfb496cca67e13b"
}
