Steps to regenerate the issue :
There are total 3 files
include.php contains :
<?php
$var1 = 5 + $var1;
?>
require.php contains :
<?php
$var2 = 5 + $var2;
?>
incvsreq.php will contain :
<?php
$var1 = 0; // Starting with 0
include('include.php'); // Includes the file so Adding 5 + 0
echo $var1.'<br/>'; // Result 5
include_once('include.php'); // Will not include as it is already included
echo $var1.'<br/>'; // Display again 5, as it was not included above
include('include.php'); // This will include again so 5 + 5
echo $var1; // Result 10
rename('include.php', '_include.php'); // Rename the file
include('include.php'); // Warning should occur on this line as the file is not present now, but the script should continue.
$var2 = 0; // Starting with 0
require('require.php'); // Includes the file so Adding 5 + 0
echo $var2.'<br/>'; // Result 5
require_once('require.php'); // Will not include as it is already included
echo $var2.'<br/>'; // Display again 5, as it was not included above
require('require.php'); // This will include again so 5 + 5
echo $var2; // Result 10
rename('require.php', '_require.php'); // Rename the file
require('require.php'); // ERROR should occur on this line as the file is not present now, and the script should not continue.
echo 'This is not displayed'; // This won't be displayed.
?>
Output of this script is :

I understood the Fatal Error in the last and 3rd warning from the top but how did other warnings appear ? I am little confused here. I have commented each line for better understanding.
