在浏览器中访问时，file_put_contents不起作用

Question

I use php5.6 and Apache2.4.6 in centOS7.5
I put a php file in /var/www/html

like this :

<?php    
echo (__DIR__ . "/test.text");    
file_put_contents(__DIR__ . "/test.text","test text");  

when I access this file through web browser(google chrome), file_put_contents do not function. but,when I execute this file in console, file_put_contents do function. it make test.text file.

Is this problem due to server setting? or some php function doesn't work in access by a browser?

this is httpd/error_log

file_put_contents(/var/www/html/test.text): failed to open stream: Permission denied in /var/www/html/fpc2.php on line 3

but, this file's permission is 777.

Answer 1

Right. So it is a permissions problem. You need to make sure that the "user" that runs the php code has permission to write into the directory. I don't know to which user to give the permission, but it may be "web". Try:

sudo chgrp -R web /var/www/html

then

sudo chmod -R g+w *
