Please explain how to create PHP's Phar stubs - php

Question

I'm trying to create a very simple PHP CLI application that can be run as a phar file from the command line:
# php myProject.phar
This is what I've tried so far:
My Project
My project is in a directory called MyProject and it has these two files in it:
|-- createPhar.php
`-- bootstrap.php
bootstrap.php
The bootstrap.php file contains this:
<?php
print phpversion() . PHP_EOL;
print 'i am some script' . PHP_EOL;
When I run this script from my Ubuntu command line:
# cd MyProject
# php bootstrap.php
I get the following output:
5.3.2-1ubuntu4.9
i am some script
createPhar.php
The createPhar.php file is meant to turn the project into Phar archive.
It looks like this:
<?php
$phar = new Phar('MyProject.phar');
$phar->addFile('bootstrap.php');
$phar->setStub( $phar->createDefaultStub('bootstrap.php') );
When I run that script...
# php createPhar.php
... a new file called MyProject.phar is created in my project's directory.
|-- bootstrap.php
|-- createPhar.php
`-- MyProject.phar
Now here's the problem
When I run the phar file...
# php MyProject.phar
...I expect to see the same the same output that I got when when I ran the bootstrap.php script.
Instead I see nothing. No output at all. This implies that my bootstrap.php script is not being included by the default stub that was created by $phar->createDefaultStub('bootstrap.php')
I think I am misunderstanding how Phars and their stubs are being created. Could you, please, explain where I have gone wrong.

Answer 1

To answer my own question.
The method outlined in my question, above, is one correct way to create a phar / phar stub.
The reason why it did not work for me and did work for Mario (see his comment below the question), is because I had Suhosin installed and needed to tweak the settings.
Fixed using the technique outlined here:
To fix, put:
suhosin.executor.include.whitelist="phar"
in /etc/php5/cli/php.ini

you could also do it like this:
bootstrap.php;
<?php
function go() {
print phpversion() . PHP_EOL;
print 'i am some script' . PHP_EOL;
}
then:
php -r "require
'phar://Myproject.phar'; go();"
or don't have a function and it will execute whatever commands you have in there, but typically you would have some functions or class files in the phar.
