Your problem description

When several source files are included/required, the magic constant contains wrong data. Code snippet contains 3 files:

test.php:
<?php
echo FILE . ' - ' . LINE . "\n";
require_once('test2.php');
echo FILE . ' - ' . LINE . "\n";
?>
test2.php:
<?php
echo FILE . ' - ' . LINE . "\n";
require_once('test3.php');
echo FILE . ' - ' . LINE . "\n";
?>
test3.php:
<?php
echo FILE . ' - ' . LINE . "\n";
?>

Expected result differs from the actual result. This bug makes debugging more difficult.

Expected results

test.php - 2

test2.php - 2

test3.php - 2

test2.php - 4

test.php - 4

Current results

test.php - 2

test2.php - 2

test3.php - 2

./test3.php - 4

test2.php - 4

Additional information

debug_backtrace() function is also affected by this bug, but there line number is also not working correctly, returning always 1:

<?php
    echo "TEST:\n"
    var_dump(debug_backtrace());
?>

The above code results in:

TEST:
array(2) {
[line] =>
int(1)
[file] =>
string(8 'test.php')
}

This can be related with https://github.com/symisc/PH7/issues/20

This is the one bug i ran into thats when i decided to give up on my project

Unfortunately this is a bug in basic functionality and we have to fix it. This will make any kind of debugging harder.

Im looking into this

i have completed one part but for the life of me i cant think how todo replace ../ etc with the actual dir i will commit changes into file_magic branch shortly i hope the unix eqiv works too but the win32 version does

This is connected with #3, I think. This is connected with #2, I think. There is a general problem with information about file & line position in PH7. FILE shows some trash, while debug_backtrace() simply gets currently processed file and returns only last callback instead of whole backtrace.
