Description

PHP Warning: fclose(): supplied resource is not a valid stream resource in .../src/GridFS/ReadableStream.php on line 78
This is my php code. It reads images from a MongoDB collection and display each file.
<?php
// include Composer (mongodb) extension
require '/src/composer/vendor/autoload.php';
class GridFS {
private $client;
public function __construct() {
$this->client = new MongoDB\Client("mongodb://localhost:27017");
}
public function Image($id) {
$db = $this->client->selectDatabase("myfiles");
$bucket = $db->selectGridFSBucket();
$stream = $bucket->openDownloadStream($id);
header("Content-type: image/jpg;");
echo stream_get_contents($stream);
exit;
}
public function FindFiles($limit) {
$collection = $this->client->selectCollection("myfiles", "fs.files");
$filter = [];
$options = ['limit' => $limit];
return $collection->find($filter, $options);
}
}
$id = isset($_GET['id']) ? urldecode($_GET['id']) : null;
$gfs = new GridFS();
if(isset($id)) {
$gfs->Image($id);
}
?>
<html>
<head><title>ImageFiles</title></head>
<body>
<?php
$files = $gfs->FindFiles(10);
foreach ($files as $file) {
$id = $file["_id"];
echo "<h2>ID: $id</h2>\r\n";
echo "<img src='?id=$id' border='0' alt='' /><br /> \r\n";
}
?>
</body>
</html>My solution is, to hide the warning...
public function close()
{
if (is_resource($this->buffer)) {
@fclose($this->buffer);
}
}
