Phar::setStub

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)

Phar::setStub — Used to set the PHP loader or bootstrap stub of a Phar archive

说明

public function Phar::setStub(resource|string $stub, int $length = -1): true

注意: 此方法需要 将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.

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';
?>

参数

stub

A string or an open stream handle to use as the executable stub for this phar archive.

length

返回值

总是返回 true。

错误／异常

UnexpectedValueException is thrown if phar.readonly is enabled in php.ini. PharException is thrown if any problems are encountered flushing changes to disk.

更新日志

版本 说明
8.4.0 The return type is true now; previously, it was bool.
8.3.0 Calling Phar::setStub() with a resource and a length is now deprecated. Such calls should be replaced by: $phar->setStub(stream_get_contents($resource));

示例

示例 #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;
}
?>

以上示例会输出：

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(); ?>"
