Description:
------------
With expose_php off I expect to have no logo displayed on php_info(). http://php.net/manual/ini.core.php#ini.expose-php says: "... affected the output of phpinfo(), as when disabled, the PHP logo and credits information would not be displayed."

But actually the logo is displayed when running simple php_info(). See also http://stackoverflow.com/a/36356058/22470

Test script:
---------------
<?php

// expose_php must be off in php.ini
// It can't be tested with 3v4l.org since php_info() is disabled there!

ob_start();
phpinfo();
$out = ob_get_contents();
ob_end_clean();


echo 'expose_php is set to: '.var_export(getenv('expose_php'), 1)."\n";
echo 'Logo is present: '.var_export(preg_match('~alt="PHP logo"~', $out), 1);





Expected result:
----------------
expose_php is set to: false
Logo is present: 0

Actual result:
--------------
expose_php is set to: false
Logo is present: 1
