Packaging a PHP application

Question

I am trying to create a .phar file from my web application. Following the php documentation's example I tried the following for this purpose. ``` <?php $srcRoot = __DIR__ . "/../app"; $buildRoot = __DIR__ . "/../build"; $p = new Phar("$buildRoot/build.phar", 0, 'build.phar'); $p->buildFromIterator( new RecursiveIteratorIterator( new RecursiveDirectoryIterator($srcRoot) ), $srcRoot ); ``` However I got the following error. I dont have any idea about the error. What is wrong with the code? ``` PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message 'Iterator RecursiveIteratorIterator returned a path "D:\site\app" that is not in the base directory "D:\site\app"' in D:\site	ools\create-phar.php:7 ```

Accepted Answer

The source of the problem is that `RecursiveDirectoryIterator` also lists the dot files - `.` and `..`. When iterating over `/path/to/foo` it also lists `/path/to/foo/.` and `/path/to/foo/..` which goes to the parent directory - outside the base directory.

Thus you have to prevent the inclusion of the ".." files, which is most easily achieved with `FilesystemIterator::SKIP_DOTS` as second parameter to DirectoryIterator:

```
new RecursiveDirectoryIterator($srcRoot, FilesystemIterator::SKIP_DOTS)
```
