Re: system, exec, shell_exec, passthru

Use exec() instead of system() and pass in args for output and error number and then you'll get an error number telling you what went wrong. You'll have to look up the error number in a shell with 'perror' (man perror) unless you dig my modest extension to do it from PHP: http://l-i-e.com/perror On Mon, August 14, 2006 10:23 am, p.willis@telus.net wrote: > 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.
