Its not clear in the docs but __HALT_COMPILER() is required in the stub.
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
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
成功时返回 true， 或者在失败时返回 false。
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 |
|---|---|
| 8.3.0 |
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(); ?>"

If your stub has a namespace, it is used for each include that doesn't define one.

One thing I had alot of problems with, is that i can't set the stub unless I put the whole operation inside of a try/catch block!
If i remove the try/catch block it will error our and not write the stub with the content i want it to have.
