phar文件的路径是什么

Question

I have created a phar file of my framework. The way you run cron-jobs in the framework is by calling executing the pharfile on the command line:

php path/to/archive.phar cron -r /path/to/site

The bootstrap file in the archive used to compare the path of _ FILE _ with the resolved path of the executed command to determine that it had been executed directly.

The question is: Is it possible to get the filename of the phar-file from within the phar file, and how?

That is: what is the alternative to _ FILE _ in phar-files?

Answer 1

You can use it:

<?php
$a = Phar::running(); // $a is "phar:///path/to/my.phar"

As in docs .

Answer 2

I've done a bit of research on the matter and it seems it is impossible without incurring too much overhead.

The only plausible way I've found is by opening the "suspect" gotten from $argv[0] and check by inspecting the contents - however, that involves a lot of extra disk IO.
