范例
Example #1 A Phar::mapPhar() example
mapPhar should be used only inside a phar's loader stub. Use loadPhar to load an external phar into memory.
Here is a sample Phar loader stub that uses mapPhar.
<?phpfunction __autoload($class){ include 'phar://me.phar/' . str_replace('_', '/', $class) . '.php';}try { Phar::mapPhar('me.phar'); include 'phar://me.phar/startup.php';} catch (PharException $e) { echo $e->getMessage(); die('Cannot initialize Phar');}__HALT_COMPILER();
