Hi, Thank you for this. It's the only one that worked. Maybe you also know how to make the upload publicly shared?
Thank you.

Works well, thanks for the example!

Any idea how to specify a folder path for the upload? I tried via the bucket name, ie, "bucket/folderpath/subfolder" but this didn't work.

Suggestions?

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
