ISO9660 Stream Wrapper for PHP

PHP Stream Wrapper for ISO9660 files (.iso files)

Usage

Install using Composer:

$ composer require vdechenaux/iso-9660

Register the Stream Wrapper:

\ISO9660\StreamWrapper::register();

Use it, with any function which supports stream wrappers:

// Get the content
file_get_contents('iso9660://path/myIsoFile.iso#song.mp3');

// Get the size
filesize('iso9660://path/myIsoFile.iso#song.mp3');

// Check if ISO file contains a file
file_exists('iso9660://path/myIsoFile.iso#song.mp3');

// List files
$iterator = new RecursiveTreeIterator(new RecursiveDirectoryIterator('iso9660://myIsoFile.iso#'));
foreach ($iterator as $entry) {
    echo $entry.PHP_EOL;
}

// Get a stream on a file contained in the ISO file
// Here, a PNG file
$stream = fopen('iso9660://myIsoFile.iso#image.png', 'r');
fseek($stream, 1); // Skip 1st byte
$header = fread($stream, 3); // We should get "PNG"

// Etc...

You must separate the iso file and the internal path with a #, even if the right part is empty, like in above examples.

You can use the \ISO9660\Reader class if you don't want to use native PHP functions.

Custom context options

You can configure some behaviors of the reader:

• showHiddenFiles (boolean, default: false) Set it to true to see/read hidden files.

To use options, you have to do something like this:

$opts = [
    'iso9660' => [
        'showHiddenFiles'  => true,
    ]
];

$context  = stream_context_create($opts);

file_get_contents('iso9660:///tmp/file.iso#hidden.mp3', false, $context);

If you are using the \ISO9660\Reader class, you can use theses options by passing an \ISO9660\ReaderOptions object to the constructor.

Read from an optical drive

As this package is an ISO9660 implementation, you can directly read an optical drive by doing something like this:

$iterator = new RecursiveTreeIterator(new RecursiveDirectoryIterator('iso9660:///dev/cdrom#'));
foreach ($iterator as $entry) {
    echo $entry.PHP_EOL;
}

By using /dev/cdrom instead of an ISO file, you can directly interact with the hardware, without mounting the disc in the OS.

Why ?

Why not ? 🤷‍♂️

I made it only for fun. I hope someone will find a usage 😁
