范例

A Phar::getStub() example

<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
echo $p->getStub();
echo "==NEXT==\n";
$p->setStub("<?php
function __autoload($class)
{
    include 'phar://' . str_replace('_', '/', $class);
}
Phar::mapPhar('myphar.phar');
include 'phar://myphar.phar/startup.php';
__HALT_COMPILER(); ?>");
echo $p->getStub();
?>

以上例程会输出：

<?php
 __HALT_COMPILER(); ?>
==NEXT==
<?php
function __autoload($class)
{
    include 'phar://' . str_replace('_', '/', $class);
}
Phar::mapPhar('myphar.phar');
include 'phar://myphar.phar/startup.php';
__HALT_COMPILER(); ?>
