1.2.301. Could Use __DIR__¶
Use __DIR__ constant to access the current file’s parent directory <https://www.php.net/`directory>`_.
Avoid using dirname() on __FILE__. __DIR__ has been introduced in PHP 5.3.0.
<?php
// Better way
$fp = fopen(__DIR__.'/myfile.txt', 'r');
// compatible, but slow way
$fp = fopen(dirname(__FILE__).'/myfile.txt', 'r');
// Since PHP 5.3
assert(dirname(__FILE__) == __DIR__);
?>
