New Comment:
Thanks for looking into my problems with exec() at the latest PHP.
Example for actual code, as in application (was running nicely in earlier PHP
installations, but not under PHP 2.4 anymore):
$str1Name = "C:\Map Maker\MMmacro.exe";
$str2Name = "command=remove layer";
exec(chr(34).$str1Name.chr(34).chr(32).chr(34).$str2Name.chr(34));
I am using a GIS called Map Maker, with powerful MMmacro functions
(www.mapmaker.com). 'remove layer' is one of the most basic parameters of
MMmacro.
A more simple test version also failed:
$str1Name = "C:\Windows\Notepad.exe";
exec($str1Name);
I also tested, all without success:
- with bat file, which then calls notepad.exe
- with exe/bat in different folders: document root (C:\xampp\htdocs) or from
calling directory (C:\xampp\htdocs\lupmis_s)
- with 'start .....'
- with popen
- with exec( .... < file.in > file.out 2> nul", $output);
- with exec(....,$output, $return);
- with exec("ping google.com", $output, $return);
-------------
My environment:
PHP 5.4.4 (VC 9)
Apache 2.4.2
Xampp 'default' installation 1.8 on C:\xampp
Apache with PHP, MySQL running as services
Win 7 Home Premium / 64 bit
4 GB RAM
HP Pavilion g7 Notebook
Bought in Germany, but OS and all programs installed in English
Running as administrator
Total application has > 220 PHP programs, with > 250 exec calls.
If you give me your full email address, I can also send you the php.ini and
httpd.conf.
Thanks for any advice
Gerhard

Tell us which command you use and how you call it, along with the parameters
(external files and the likes can be sent to my email (my handle @ php.net).

We need something to reproduce it, as we can't.
Do you have a common exe app that we can use to try to reproduce the problem
you
are experiencing?

Despite various updates and fixes, I dont think, the 'exec problem' in PHP is
solved.
In my PHP programs, I have plenty of calls from PHP 5.3.0 to external exe files
with 'exec(...)' (on local drive, with Apache 2.2.12, installed through xampp
1.7.x, on Vista and Win 7) on dozens of computers: Everything works well.
But when I migrated to new computer with PHP 5.4.4 (VC9, with Apache 2.4.2,
installed through xampp 1.8, on Win 7/64), the SAME exec() calls dont work
anymore. No display, no error messages, no entries in log file. Configuration
in httpd.conf and php.ini are identical.
Any advice is appreciated. I also posted in xampp forum
(http://www.apachefriends.org/f/viewtopic.php?f=6&t=51537, with confirmation,
that I am not the only one with this problem....).
Kind regards
Gerhard
