phpinfo() is not working it shows blank page but other php working

Question

I am completely lost as to why this is happening. I am on a server x10hosting. I have a PHP file named "phpinfo.php". Inside this file it says

<?php phpinfo(); ?>

It doesn't say <? phpinfo(); ?>

For all I can tell it should be perfectly fine. If I try other PHP code they work.

For example

<?php
echo '<div>hello World</div'; 
?>

works perfectly. What could possibly be the problem?

Answer 1

phpinfo() is disabled for free accounts on that particular hosting provider. You have to upgrade if you want access to phpinfo().

Answer 2

Use error_reporting(E_ALL); and ini_set('display_errors', TRUE); you might find an error saying that phpinfo is on the restricted functions list (x10hosting may not want anyone to find out their configurations/ weaknesses etc.).

Answer 3

Check your php.ini file, and grep for disable_function:

cat php.ini | grep -in "disable_function"

If the output has phpinfo in this line as such:

386:disable_functions = show_source, system, shell_exec, passthru, exec, phpinfo, popen, proc_open

edit the file and remove phpinfo from this line and save. You may need to restart httpd

service httpd restart
