php-tmpfile

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, optionally with custom HTTP headers
• Save file locally

Examples

<?php
use mikehaertl\tmp\File;

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

// send to client for download
$file->send('home.html');
// ... with custom content type (autodetected otherwhise)
$file->send('home.html', 'application/pdf');
// ... for inline display (download dialog otherwhise)
$file->send('home.html', 'application/pdf', true);
// ... with custom headers
$file->send('home.html', 'application/pdf', true, [
    'X-Header' => 'Example',
]);

// 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 mikehaertl\tmp\File;

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

Default HTTP headers can also be added:

<?php
use mikehaertl\tmp\File;

File::$defaultHeader['X-Header'] = 'My Default';

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