function Introduction

Web developers often need to deal with all kinds of information uploaded by users, such as pictures, attachments, documents, and so on, which are generally stored in the server's local space. However, in a distributed environment such as ACE, storage and locality are not conducive to the automatic expansion and recycling of servers determined by processing access capabilities, so ACE provides storage services. Developers can gain distributed storage capabilities and space through the storage service.

Instructions for use

Using storage eliminates the need for developers to add any library files to their code without requesting their own keys, without having to manually create a stored "folder" name, just calling an interface similar to a file operation.

Reference sample







$file _url = $storage->upload ("Test.jpg", "title.jpg");
$file _url would be xxx.aliapp.com/aliyun_ce_storage/title.jpg
}
$file _lists = $storage->getlist ();
if ($stoage->fileexists ("title.jpg")) {
$content = $storage->read ("title.jpg");
}
?>
