createPhar.php

<?php
# Create an executable phar

# Name of our archive.
$phar = new Phar("myscript.phar");

# Have to do buffering to make things executable.
# See http://stackoverflow.com/questions/11082337/how-to-make-an-executable-phar
$phar->startBuffering();

# Default executable.
$defaultStub = $phar->createDefaultStub('bin/myscript.php');

# Build from the project directory. Assumes that createPhar.php (this file) is in the project root.
$phar->buildFromDirectory(dirname(__FILE__));

# Add the header to enable execution.
$stub = "#!/usr/bin/env php \n" . $defaultStub;

# Set the stub.
$phar->setStub($stub);

# Wrap up.
$phar->stopBuffering();
