<?php
// make sure it doesn't exist
@unlink('brandnewphar.phar');
try {
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
$p['file.php'] = '<?php echo "hello";';
$p->setMetadata(array('bootstrap' => 'file.php'));
var_dump($p->getMetadata());
} catch (Exception $e) {
echo 'Could not modify phar:', $e;
