Re: php exec()

Hi, I'm not a Linux guru, so maybe my question is stupid, but are you sure the command prints its output to the *standard* output? Z cheesiong wrote:

hi Chris,

i found out that when execute ipkg, the return is before the header. root [ /srv/www/test ]# /program/php-5.2.6/bin/php-cgi ipkg.php ipkg version 0.99.163 X-Powered-By: PHP/5.2.6 Content-type: text/html Array ( ) which is different than the whoami program. root [ /srv/www/test ]# /program/php-5.2.6/bin/php-cgi whoami.php X-Powered-By: PHP/5.2.6 Content-type: text/html the result of execwhoami is root can you see the different? regards,-keo On Mon, Nov 3, 2008 at 2:12 PM, cheesiong <bluecolour.sz@gmail.com>

Change it, su, change it back. Looking at apache logs won't tell you

much

if you don't try something. Are you running selinux? <http://169.254.0.20>] /opt/ipkg-0.99.163/bin/ipkg-cl: Permission

That one's pretty easy. -- Postgresql & php tutorials http://www.designmagick.com/

What about making an exec call, but piping the results of that call to a text file. That way, it will be in a file that is easily accessed from other parts of your site. I'm not sure which is more expensive, a call to ifconfig, or a file read. Ash www.ashleysheridan.co.uk
