Pajoye,

I didn't find any documentation on the service sensitivity of the new PHP.

You might be right, that the eof of the console stream is not taken care 
properly, but in my case the system is now working (again).

this is documented, the shell/exec permissions have to be given.

However I do not think it is related to the original issue which is caused by a 
real bug in the php stream, where the eof of the console stream is not 
correctly 
detected and ends in an endless loop.

After many hours of testing, I managed to solve my problem of exec() calls in 
PHP. This might be useful also for other developers, as I have seen many 
struggling with te same problem.

1. xampp must be installed in real (!) administrator mode (in Windows 7 / 32 & 
64 bit). 

2. In many environments, Apache and MySQL should not run as services, but be 
manually started (even not with interaction with desktop).

I have put a step-by-step procedure to troubleshoot at:

(Ignore the references to our system LUPMIS).

Good luck to everybody 
Gerhard

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).
