A convenience class for temporary files.

Features

• Create temporary file with arbitrary content
• Delete file after use (can be disabled)
• Send file to client, either inline or with save dialog
• Save file locally
• Inject callback with custom file sender

Examples

<?php
use devnullius\tmp\File;

$file = new File('some content', '.html');

// send to client for download
$file->send('home.html');

// save to disk
$file->saveAs('/dir/test.html');

// Access file name and directory
echo $file->getFileName();
echo $file->getTempDir();

If you want to keep the temporary file, e.g. for debugging, you can set the $delete property to false:

<?php
use devnullius\tmp\File;

$file = new File('some content', '.html');
$file->delete = false;

If you want to use other way to send files you can give callback as in example (Here is Yii2 response sendFile)

<?php
use devnullius\tmp\File;

$file = new File('some content', '.html');

$file->setResponseMethod(static function ($_filename, $filename) {
    \Yii::$app->response->sendFile($_filename, $filename);
});
$fileName = 'greatFileName.txt';
// and if there is set any response method it's going to be executed
$file->send($fileName);
