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

### 说明

public function Phar::setDefaultStub(?string `$index` = `null`, ?string `$webIndex` = `null`): 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 a convenience method that combines the functionality of Phar::createDefaultStub() and Phar::setStub().

### 参数

`index`

  Relative path within the phar archive to run if accessed on the command-line

`webIndex`

  Relative path within the phar archive to run if accessed through a web browser

### 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 | Phar::setDefaultStub() now has a tentative return of true.
8.0.0 | `webIndex` is nullable now.

### 示例

        $phar = new Phar('myphar.phar');
        $phar->setDefaultStub('cli.php', 'web/index.php');
        // this is the same as:
        // $phar->setStub($phar->createDefaultStub('cli.php', 'web/index.php'));
    } catch (Exception $e) {
        // handle errors
    }
