README

This package provides a PSR-7-compatible StreamInterface implementation, along with an extended UlovDomov\Stream\FileStream class that adds more.

Installation

Run:

composer require ulovdomov/php-stream

Usage

Create UlovDomov\Stream\FileStream

You can create stream from:

• resource
• string
• int
• float
• bool
• \Psr\Http\Message\StreamInterface
• callable
• \Iterator
• null

$stream = \UlovDomov\Stream\FileStream::create('my stream content');

For file path:

// stream for reading
$stream = \UlovDomov\Stream\FileStream::createForPath(__DIR__ . '/file.pdf');

// stream for writing
$stream = \UlovDomov\Stream\FileStream::createForPath(__DIR__ . '/file.pdf', 'w');

Additional features

/** @var UlovDomov\Stream\FileStream $stream */

// get mime type
$stream->getMimeType(); // string: text/plain

// get file extension (can return null for application/octet-stream or unknown mimetype)
$stream->getExtension(); // string: txt

// save content as file
$stream->saveAs(__DIR__ . '/my-new-file.jpg');

Utils

Method tryFopen

Replacement for fopen, it returns a resource; throws a StreamException on error.

/** @var resource $file */
$file = \UlovDomov\Stream\Utils::tryFopen(__DIR__ . '/my-file.pdf');

Method mimetypeToExtension

Get file extension. Can return null for application/octet-stream or not implemented mimetype.

\UlovDomov\Stream\Utils::mimetypeToExtension('application/pdf');
// "pdf"

Method isOctetStream

Get true if mimetype is application/octet-stream.

\UlovDomov\Stream\Utils::isOctetStream('application/octet-stream');
// true

\UlovDomov\Stream\Utils::isOctetStream('text/json');
// false
