PHPMusicXML is a robust PHP library for creating, manipulating, and converting music notation files. It specializes in converting MIDI files into highly readable MusicXML format, with advanced logic to handle complex musical notation and lyrics. Each element in the MusicXML schema is represented by a dedicated class model within the library.

1. Advanced Lyric Spacing: Automatically calculates and intervenes in note positioning (default-x) to prevent lyric overlaps, ensuring professional-looking scores.
2. Channel Filtering: Convert specific MIDI channels or the entire file.
3. Percussion Support: Automatic mapping of MIDI Channel 10 to standard MusicXML percussion notation.
4. Chord Detection: Intelligent detection of simultaneous notes.
5. High Compatibility: Optimized for popular notation software like MuseScore, Sibelius, and Finale.
6. Comprehensive Models: Implements elements based on the MusicXML 4.0 Reference.

1. Read, modify, and write MusicXML files.
2. Convert MIDI to MusicXML (Compressed .mxl or Uncompressed .xml).
3. Convert MusicXML to MIDI (Experimental).

The easiest way to convert files is using the convert.php script:

Basic Conversion:

php convert.php "input.mid"

Select Specific Channels (e.g., Vocal on Channel 4):

php convert.php "input.mid" --channels=4

Bulk Conversion:

php convert.php --dir="midi_folder"

For more detailed CLI instructions, please refer to manual.md.

You can integrate PHPMusicXML directly into your project.

Uncompressed MusicXML is a standard XML file compatible with most notation software.

<?php

use MusicXML\MusicXML;

require_once "inc.lib/autoload.php";

$musicXML = new MusicXML();
try
{
    $midi = $musicXML->loadMidiFile("test.mid");
    $xml = $musicXML->midiToMusicXml($midi, "Test", "4.0", "xml");
    file_put_contents("test.xml", $xml);
}
catch(Exception $e)
{
    echo $e->getMessage();  
}

Compressed MusicXML is zipped files containing XML file according to https://www.w3.org/2021/06/musicxml40/, mimetype, and META-INF/container.xml

<?php

use MusicXML\MusicXML;
use MusicXML\Util\MXL;

require_once "inc.lib/autoload.php";

$musicXML = new MusicXML();
try
{
    $midi = $musicXML->loadMidiFile("test.mid");
    $mxl = new MXL();
    $xml = $musicXML->midiToMusicXml($midi, "Test", "4.0", "xml");
    file_put_contents("convert.mxl", $mxl->createMxl("Test", $xml));
}
catch(Exception $e)
{
    echo $e->getMessage();  
}

Another way

<?php

use MusicXML\MusicXML;

require_once "inc.lib/autoload.php";

$musicXML = new MusicXML();
try
{
    $midi = $musicXML->loadMidiFile("test.mid");
    $mxl = $musicXML->midiToMusicXml($midi, "Test", "4.0", "mxl");
    file_put_contents("convert.mxl", $mxl);
}
catch(Exception $e)
{
    echo $e->getMessage();  
}

Thank you https://github.com/robbie-cao/ for your library at https://github.com/robbie-cao/midi-class-php/. We learn much about MIDI file format and using code from your library and attach it to our code. We need MIDI parser before create MusicXML file from a MIDI file.
