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.
<?php
function __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();
