, Bu benim için aynı görünüyor, ama emin değilim
dirname(__FILE__) kullanan pek çok proje var çünkü.
Their result is exactly the same; böylece, o fark yok.
For example, the two following lines :
var_dump(dirname(__FILE__));
var_dump(__DIR__);
Ikisi aynı çıktı verecektir:
string '/home/squale/developpement/tests/temp' (length=37)
But, there are at least two differences :
__DIR__ only exists with PHP >= 5.3
dirname(__FILE__) strong> daha yaygın olarak kullanılmaktadır neden olan__DIR__ is evaluated at compile-time, while dirname(__FILE__) means a function-call and is evaluated at execution-time
As, as a reference, see the Magic constants section of the manual (quoting) :
__DIR__: The directory of the file.
If used inside an include, the directory of the included file is returned.
This is equivalent todirname(__FILE__).
This directory name does not have a trailing slash unless it is the root directory.
(Added in PHP 5.3.0.)
