Issues/pull requests
--------------------

[](#issuespull-requests)

This repository is a subtree split of the [iqb/Morgue](https://github.com/iqb/Morgue) repository so it can be required as a standalone package via composer. To open an issues or pull request, please go to the [iqb/Morgue](https://github.com/iqb/Morgue) repository.

Installation
------------

[](#installation)

Via [composer](https://getcomposer.org):

```
composer require iqb/substream
```

Usage
-----

[](#usage)

The stream wrapper is registered for the `iqb.substream://` protocol. To use as substream, just open a new like that:

```
use const iqb\stream\SUBSTREAM_SCHEME;

$originalStream = fopen('filename', 'r');
$offset = 25;
$length = 100;

// Provide the stream via a stream context
$context = stream_context_create([SUBSTREAM_SCHEME => ['stream' => $originalStream]]);
$substream = fopen(SUBSTREAM_SCHEME . "://$offset:$length", "r", false, $context);

// Alternatively, you can just put the stream into the URL
$substream = fopen(SUBSTREAM_SCHEME . "://$offset:$length/$originalStream", "r");

fseek($orignalStream, 50);
fseek($substream, 25);

// Will not fail
assert(fread($originalStream, 50) === fread($substream, 50));
```
