Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

I did another test. It is only the include that keeps the file handle open.
If I change to be include_once, it does not happen.
Unfortunately the magento ecommerce package uses include and there are
thousands of files that would have to be changed to use include_once instead --
and it would probably break the ecommerce package.
This is a bug in PHP 5.2.6 and was in PHP 5.2.5 too.

Here is reproducible source code:
<?php
echo '<br>';
echo 'this is test1.php';
echo '<br>';
echo '<br>now include include1.php';
include ('include1.php');
echo '<br>';
require_once('require1.php');
?>
The lsof output is:
httpd 22255 apache 28r REG 0,211 63 81173388
/var/www/vhosts/bubbleyou.com/httpdocs/test2.php
httpd 22255 apache 29r REG 0,211 65 81173382

httpd 22255 apache 31r REG 0,211 65 81173382

httpd 22255 apache 33r REG 0,211 63 81173388

httpd 22255 apache 36r REG 0,211 65 81173382
/var/www/vhosts/bubbleyou.com/httpdocs/include1.php
And every time I rerun the above code I get more open file handles for these
same files.
When I run under PHP 5.2.0, I don't get this result.

PHP Version 5.2.6
Apache Version Apache/2.2.3 (CentOS)
Apache API Version 20051115
Reproduce code:
---------------
All includes leave the .php file open.
I am running the magento e-commerce package.
The includes are standard.
This bug was reported as bug #43105 and the change log says it was
fixed for php 5.2.6 and that is what I am running per above phpinfo.
Expected result:
----------------
When I run lsof -u apache | grep magento I do not expect to see any
open .php files.
Actual result:
--------------
I have 1900 open files. Many are multiple file handles for the same file. I
eventually get "too many open files" error. Some example output from
lsof -u apache | grep magento are:
