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 Phar::setStub(string $stub, int $len = -1): bool

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.
len

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.

范例

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;
}
?>

以上例程会输出：

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(); ?>"

Its not clear in the docs but __HALT_COMPILER() is required in the stub.

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.
