Web forms are a common way how to interact with a client using PHP. We wanted to move the form handling to a client side. So, web forms generated from PHP scripts are now handled on a client side without knowing about additional configuration. You just specify a request method and handling script. Superglobals $_GET and $_POST work as you expect.

The example of using web forms can be found in

When you generate a web form from a PHP script, PhpScriptProvider turns the form handling to a client side, where the provider finds the handling script of the form.

Loading and downloading files are possible as well. However, we need specialized functions to manage it.

The example of using web forms can be found in

Uploading file#

When a client uploads a file to the webform and sends it, we can get information about sent files in superglobal $_FILES. When you want to read a file content, you have to use GetBrowserFileContent($fileId), which returns Base64 encoded content of the file by the given id. This id has every object returned from $_FILES.

Creating file#

Because of the browser environment, you have to use the specialized function for creating a file. CreateFile(string $data, $contentType, $name) will create a browser representation of the file with given data, type, and name.

Downloading file#

Then you can download an already existing file by DownloadFile($fileId), which finds the file in the memory and start to download it to a client PC.

You can see an example of creating a CSV file and downloading it to a client below.


$file = CreateFile('Hello, world',"text/csv", "graph.csv");
