Phar存档没有Symfony文件系统的读写权限 [英] Phar archive no read and write permissions with symfony filesystem

问题描述

我创建了一个cli应用程序，该应用程序尝试使用symfony 3 fileSystem组件创建文件.一切正常，但是如果我将应用程序放在phar存档中，symfony无法写入该文件.

i have created a cli app which tries to create a file with symfony 3 fileSystem component. All works fine, but if i put the app in a phar archive symfony can't write the file.

这是我创建phar存档的方式:

This is how i created the phar archive:

<?php
$phar = new Phar('app.phar', 0, 'app.phar');
$phar->buildFromDirectory(dirname(__FILE__) );
$phar->setStub($phar->createDefaultStub('app.php'));

app.php调用symfony文件系统组件:

The app.php call the symfony filesystem component:

<?php 

....

$this->fileSystem->dumpFile(
    'testfile.txt',
    'my test content'
);

如果我直接执行app.php，这很好.但是，如果我将其作为.phar执行，则会收到此消息.

This works fine if i execute app.php directly. But if i execute it as a .phar i get this message.

[Symfony\Component\Filesystem\Exception\IOException]  
Failed to create ".": mkdir(): File exists.

其他操作，例如echo正常运行. 我认为，phar存档的IO操作存在问题.但是我不理解问题出在哪里.在我的php.ini中，配置了phar.readonly = Off.

Other operations like echo working fine. In my opinion i think, that the phar archive has a problem with IO operations. But i don't unterstand whats the problem. In my php.ini is phar.readonly=Off configured.

我希望有人能给我提示. :)

I hope someone can give me a hint. :)

推荐答案

Phar具有不同的路径结构，而symfony方法确实具有dirname($filename);

Phar's have a different path structure, and that symfony method does dirname($filename); https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Filesystem/Filesystem.php#L679

尝试定义完整路径.

$path = '.';
if (!empty($pharPath = \Phar::running(false))) {
    $path = dirname($pharPath);
} 

$this->fileSystem->dumpFile(
    $path.'/testfile.txt',
    'my test content'
);
