[PHP] Re: system, exec, shell_exec, passthru
Hi,
I can run any external program like ls, cp, uptime...
But if a try to run my shell script a get error.
$passwdexe = sudo /usr/bin/webpasswd;
$user=$_POST[name];
$passwd=$passwdexe $user 123456;
echo $passwd;
$result = system($passwd);
Resultat from the web, sudo /usr/sbin/webpasswd billy 12345678
and from the error_log, couldn't read file ./usr/sbin/webpasswd.: no
such file or directory.

Hello,
I am trying the run an external application with
command line arguments using PHP under linux.
ie:
$command=myprog $arg1 $arg2 textfile.txt;
system(echo \$command\ test.txt);
system($command);
$handle=fopen(textfile.txt,r);
if($handle!=NULL)
{
while(!feof($handle))
{
...
}
fclose($handle);
}
I test my input arguments for the 'system' call by dumping
the command into a text file. I can then test the command in the
console. The commands work fine when run from the console.
The commands don't work when run through the system command.
I have tried system, exec, passthru, and shell_exec to no avail.
Am I missing some permissions thing in my php.ini file?
Thanks for any insight,
Peter
Looking at your $command, there is no path in front of it. It's likely
that PHP's shell doesn't have the program in its PATH. Try manually
specifying the full path to the command:
$command=/home/peter/myprog $arg1 $arg2 textfile.txt;
(or whatever the path is)
Keep in mind that under linux, (unlike DOS), you CANNOT execute
applications in the same directory without a path. Even if the program
is in the same directory as your present working directory (which is
usually where the PHP script is located), you'd have to do ./myprog as
a relative path.

No, it not on... safe_mode Off Off safe_mode_exec_dir no valueno value safe_mode_gid Off Off safe_mode_include_dir no valueno value .M Adam Zey wrote: Michael Jonsson wrote: Hi, I can run any external program like ls, cp, uptime...

It looks like safe mode might be on. Create a new PHP script with nothing but the command phpinfo(); in it, and view it in a browser. To see if safe mode is on, look for the setting safe_mode. The line below it is safe_mode_exec_dir. If safe mode is on, you'll need to put your program (webpasswd) into that directory to execute it.
