Answers for "dirname(__dir__) in php"

PHP

include php __DIR__

PHP scripts run relative to the current path (result of getcwd()), 
not to the path of their own file. 
Using __DIR__ forces the include to happen relative to their own path.
CORRECT: in file2.php: include (__DIR__ . "/file3.php");
To demonstrate:
- file1.php
- dir/
   - file2.php
   - file3.php
If file2.php includes file3.php like this: include `file3.php`.
It will work fine if you call file2.php directly. 
However, if file1.php includes file2.php, 
the current directory (getcwd()), will be wrong for file2.php, 
so file3.php cannot be included.

php dirname

// dirname ( string $path [, int $levels = 1 ] ) : string

<?php
echo dirname("/etc/passwd") . PHP_EOL;
echo dirname("/etc/") . PHP_EOL;
echo dirname(".") . PHP_EOL;
echo dirname("C:\\") . PHP_EOL;
echo dirname("/usr/local/lib", 2);
