(PHP >= 5.3.0, PECL phar >= 1.0.0)
Phar::setStub — Used to set the PHP loader or bootstrap stub of a Phar archive
Note: This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.
This method is used to add a PHP bootstrap loader stub to a new Phar archive, or to replace the loader stub in an existing Phar archive.
The loader stub for a Phar archive is used whenever an archive is included directly as in this example:
<?php
include 'myphar.phar';
?>
The loader is not accessed when including a file through the phar stream wrapper like so:
<?php
include 'phar://myphar.phar/somefile.php';
?>
A string or an open stream handle to use as the executable stub for this phar archive.
如果成功则返回 TRUE，失败则返回 FALSE。
UnexpectedValueException is thrown if phar.readonly is enabled in php.ini. PharException is thrown if any problems are encountered flushing changes to disk.
Example #1 A Phar::setStub() example
<?php
try {
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
$p['a.php'] = '<?php var_dump("Hello");';
$p->setStub('<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>');
include 'phar://brandnewphar.phar/a.php';
var_dump($p->getStub());
$p['b.php'] = '<?php var_dump("World");';
$p->setStub('<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>');
include 'phar://brandnewphar.phar/b.php';
var_dump($p->getStub());
} catch (Exception $e) {
echo 'Write operations failed on brandnewphar.phar: ', $e;
}
?>
上例将输出：
string(5) "Hello"
string(82) "<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"
string(5) "World"
string(83) "<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"
