BTW: I am apparently not the only one:

Additionally because every time I wrote it people assuming I am using "eval", so just to clarify I don't
For debugging I am using phpStorm 2016.2.2

Hi,

thanks for the report. In order to find and fix the bug, I really do need a reproducible case. As this seems to be a remote debugging issues, please refer to https://xdebug.org/support.php#remote as to what I would require.

cheers,
Derick

Sure thing, here is the script: https://gist.github.com/Radek-Suski/660a8b820c98763304fa8617fa7c77d1
Here is the log file: https://www.dropbox.com/s/kq5sst1maot4he4/xdebug-log.log?dl=0

What really weird, I just realised, that debugging this script gives following results:

__FILE__ = "xdebug://debug-eval"
__DIR__ = "xdebug:"
$file = "/www/Neo/libraries/Sobi/index.php"
$dir = "/www/Neo/libraries/Sobi"
$dirname = "/www/Neo/libraries/Sobi"

Which means that if I assign those constants to variables, those variables are having correct values.

Regards,
Radek

Hi,

I see what happens now. You have these in the "Watches" field. PhpStorm handles watches by running the DBGp "eval" command. In the log, that looks like:

<- eval -i 62 -- JEdMT0JBTFNbJ0lERV9FVkFMX0NBQ0hFJ11bJzlmNmZiNjcxLWU0ZWItNDIyNy04Mzc2LTNhNjNkZDNiMmNmMCddPV9fRElSX18=

As the eval command really just calls PHP's eval, you get the same result:

$ php -r "echo eval('echo __FILE__;');"
Command line code(1) : eval()'d code

Xdebug *does* replace the "Command line code(1) : eval()'d code" with "xdebug://debug-eval" though.

This is something I can not change.

@derick Thank for your answer. Yet I am not sure if you are entirely correct. Yes, I have it in watches. But even if, the logical execution is failing. I am asking:

if(file_exists( __DIR__.'/file.php'))

and it returns "false". It can't be just because I have it in my "watches" because at the first time I was debugging my case, it wasn't

No, it can't be because it's in watches. But that "file_exists" would only file for real reasons. If you can reproduce this, I would use "strace -o /tmp/strace.log php script.php" and see for which file it is doing a "stat".

I know for sure that this file exists. That's how I figured out this issue

Okay - I would definitely use the strace then. There *must* be something why PHP thinks it's not there, and strace is your only hope I think.
