Description:
------------
Real PHP version (from phpinfo): PHP Version 7.0.15-0ubuntu0.16.04.4
dbase version: 7.0.0beta1

I don't know why some dbf files do not open, but when it happens the function don't closes a file descriptor, and that's bad. Don't know if I have the opportunity to close file descriptors?

I execute: php -r 'var_dump(dbase_open("/tmp/fias/NORDOC01.DBF", 0));'
output:
PHP Warning:  dbase_open(): unable to open database /tmp/fias/NORDOC01.DBF in Command line code on line 1
PHP Stack trace:
PHP   1. {main}() Command line code:0
PHP   2. dbase_open() Command line code:1
Command line code:1:
bool(false)

I know that the problem is in the dbf file. But how to close the file descriptor? The problem is that open file descriptors exceeds the limit of this process and I get the error "Too many open files"

Test script:
---------------
A test script is missing, because the problem in DBF file. File here: https://yadi.sk/d/KfqylbSg3GJSSw

Expected result:
----------------
I expect that the function will return false, as described here (http://php.net/manual/en/function.dbase-open.php) and will close the open file

Actual result:
--------------
PHP Warning:  dbase_open(): unable to open database /tmp/fias/NORDOC01.DBF in Command line code on line 1
PHP Stack trace:
PHP   1. {main}() Command line code:0

And file descriptor do not close!
