范例

A Phar::getMetadata() example

<?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;
}

  ["bootstrap"]=>
  string(8) "file.php"
