Inexistent PHP file successfully required and run?

I make tests on localhost (Windows, WAMP Server) so never bothered to test my code again after pushing them to remote server (Linux) which, after a few days, is giving this error:

failed to open stream: No such file or directory

So I looked into it and found something.

Here is the crime scene and my detective work on localhost:

echo $initEntityAutoFile;
if (file_exists($initEntityAutoFile)) {
    echo ' - EXISTS - ';
} else {
    echo ' - NOT - ';
}
$initEntityAuto = require $initEntityAutoFile; // the line giving the error
echo get_class($initEntityAuto);
echo PHP_EOL, get_include_path();

Which gives this:

/cli/aaa/bbb/ccc.php - NOT - Closure
.;C:\php\pear

Seems I'm requiring this path: /cli/aaa/bbb/ccc.php which is a relative path immediately under my project document root. No wonder my remote server doesn't find the file since it's not an absolute path at all. It should be /home/xxx/public_html/cli/aaa/bbb/ccc.php or C:/project/cli/aaa/bbb/ccc.php.

But the weird thing is, while the remote server gives an error on this, my localhost is correctly finding the file - with file_exists() returning FALSE but $initEntityAuto successfully getting the content, a closure in that file. Neither does the require raise any error, otherwise I would have found the problem and fixed it.

This is really weird. Why?

I could just correct the path and get on but this is kind of haunting me. If anybody can give an answer, I would sleep better.

===========

Additional info:

  1. The require line is in a function in a file that's very deep down the project directories, so it's not in the same directory as /cli/aaa/bbb/ccc.php.
  2. $initEntityAutoFile, a.k.a. the path string /cli/aaa/bbb/ccc.php is passed in the function as a parameter.

As suggested by @Alexey, I used getcwd() to find what the current working directory is before the require line:

  • localhost: X:\my_project
  • remote server: /home/xxx/public_html

Now that I'm requiring this path: /cli/aaa/bbb/ccc.php (with a beginning slash), on my localhost (Windows, WAMP Server), the path is automatically translated to absolute path:

X:\my_project/cli/aaa/bbb/ccc.php

So my code works properly on localhost.

However on the remote server (Linux), when I'm requiring the path /cli/aaa/bbb/ccc.php, the file system treats it as an absolute path instead of concatenating it to the current working directory because it has a beginning slash:

/cli/aaa/bbb/ccc.php

Therefore causing the "failed to open stream: No such file or directory" error.

Eventually, we have 2 solutions:

  1. Use absolute path on both localhost and remote server.
  2. Use cli/aaa/bbb/ccc.php that is without the beginning slash so both localhost and remote server would correctly treat it as a relative path and concatenate it to the current working directory to get the right path.
