Now I'm migrating my site to new server where the site was not working properly. after I debug the issue, its due to "php include not working".
so I did some testing to find the issue. for that. I just create simple html file with include tag
file name : test1.php file content:
<html lang="en">
<? include 'webcss.php' ?>
</html>
New server: Executing the file through cli
[root@localhost test]# php test1.php
<html lang="en">
<? include 'webcss.php' ?>
</html>
[root@localhost test]#
Existing server : Executing the same cli command. it shows the output.
[root@www test]# php test1.php
<html lang="en">

[root@www test]#
Both servers are same hardware, Operating system and php version. I don't know what was the reason for the same code not running on new server.
Someone please help to fix this issue. so that I can move my site to new prod datacenter.
Note : I verified the php settings on both servers by using phpinfo. both are same.
I don't have any idea what parameters I need to check.
OS: CentOS 7
PHP : 5.4.16
