Thx it works!

@markbratanov To upload into subfolder

$file_name = 'sub_bucket/subbucket/file.png';

For publicly shared objects, you need something like this:

// this access control is for project owners
$ownerAccess = new \Google_Service_Storage_ObjectAccessControl();
$ownerAccess->setEntity('project-owners-' . $projectId);
$ownerAccess->setRole('OWNER');

// this access control is for public access
$readerAccess = new \Google_Service_Storage_ObjectAccessControl();
$readerAccess->setEntity('allUsers');
$readerAccess->setRole('READER');

$obj = new \Google_Service_Storage_StorageObject();
$obj->setName($filename);
$obj->setAcl([$ownerAccess, $readerAccess]);

$storage->objects->insert(
    'my_bucket',
    $obj,
    [
        'data'       => file_get_contents($filename),
        'uploadType' => 'media',
    ]
);

Hi, thanks!

Hi, thx so much for this code snippet. Works perfectly :) 👍

I've only got one additional question. How can I add metadata with this script? Because if I upload for example a image file the standard Content-Type is always application/octet-stream which leasds to direct download on opening it via url. So I want to set it to for example image/jpeg because then I can view the file over URL and force download via readfile()if necessary.

You could specify the mimeType in opt params like this:

$storage->objects->insert(
    'my_bucket',
    $obj,
    [
        'data'       => file_get_contents($filename),
        'uploadType' => 'media',
        'mimeType' => 'image/jpeg'
    ]
);

Thank you for an example.

This example works great, thanks! The simplest way to make the upload publicly shared is:

$storage->objects->insert(
    'my_bucket',
    $obj,
    [
        'data'          => file_get_contents($filename),
        'uploadType'    => 'media',
        'mimeType'      => 'image/jpeg',
        'predefinedAcl' => 'publicRead'    // THIS LINE OF CODE MAKES FILE PUBLIC FOR READING
    ]
);

Thanks for this!
Did you have to include the entire Google cloud PHP API library? Or just the two files Client.php and Storage.php? Can I somehow just require those two files?

For this library : https://github.com/GoogleCloudPlatform/google-cloud-php#google-cloud-storage-ga
Use as following :

$bucket->upload(
fopen('data3.txt', 'r'), ['predefinedAcl' => 'publicRead']
);

how do i stored the link in db.. to load my contents
