找不到PHP包含路径

Question

I'm facing a problem when I'm trying to include a certain file. When I try to load the file I face this error :

failed to open stream: No such file or directory in ...

On the other hand , a <a href="/wT/sys/background.php">background</a> sends me directly to the file I want to include ( not the source code of it , but the output)

How come the include function cannot access the file via the given path but I can access it using a href ? *I need to get the source code of the file , not only the output , otherwise I'd just include the http://.... path *I run the php code on localhost, if it matters

I also tried to chechk whether I need to reconfigure the php.ini file but I didn't find anything useful ( Include url is allowed altough , as I said , I don't need to use it)

Any suggestion would be helpful, Thanks in advance

Answer 1

include $_SERVER['DOCUMENT_ROOT'] . '/wT/sys/background.php';

Answer 2

If file you want to include is in the lower directory as the script into which you are trying to include it, then try:

include __DIR__.'/wT/sys/background.php';

or simply

include 'wT/sys/background.php';
