Can't allow_url_fopen turn on.

Hello.
On Centos 7 with Apache 2.4 and PHP 5.4 I would like to turn on allow_url_fopen
In php.ini:

Code:

allow_url_fopen = On
allow_url_include = On

but it still looks like not eneabled.
I use this test: tt.php

Code:

<?php
$a = ini_get('allow_url_open');
if ($a === true)
    echo 'allow_url_open is ON';
else
    echo 'allow_url_open is OFF';

And it shows:

Code:

allow_url_open is OFF

I try Php 5.6 and the result is same.
How to fix this problem?

 

Better use the custom php.ini settings for the webdomain

 

I tryed to make file php.ini

Code:

allow_url_fopen = On

and put this file in the website root directory and it also does not work.
I have no idea where the problem is???

 

Double check that you are modifying the correct php.ini , do a phpinfo and modify the php.ini you see at, Loaded Configuration File field , if you enable the function right there then must work.
You can check the function status from phpinfo as well

 

How to definitely check if it works or not.
I see in info.php that
allow_url_fopen = On
but my test file show OFF and I also cannot see the pictures on generated pdf.
