Here's what the manual has for syntax for system: string system (string command [, int return_var]) So, in your example, the variable $out is an integer of the return_var. I think this only applies to *nix operations. System "Returns the last line of the command output on success, and false on failure." So, you might want to try the following instead: $out = system($cmd); echo $out; > The process execution functions/commands (exec(), passthru(), system(), and > ``) don't currently work under Win32. Try using COM to have another program > execute the batch file. That's not true. I'm able to run a variety of command line programs from the program execution functions in PHP. I'm using NT 4, Apache and can switch back and forth between PHP 3 and 4. Delbono, below is an example that runs the same command under the three program execution functions. Put this test script on your machine and check it out. The behavior of each is different. Use the one that does what you want it to. Starting and stopping mysqld should be no problem. Doing the same with Apache probably wont work. Since Apache is needed to get your PHP scripts to work. <?php $Command = "dir *.htm"; echo "<pre>\n"; echo "Command to be run: $Command\n\n"; echo "\n\n=========================================================\n"; echo "EXEC()===================================================\n"; $Return = exec("$Command"); echo "\n\n----Returns----\n"; echo "$Return"; echo "\n\n\n\n=========================================================\n"; echo "PASSTHRU()===============================================\n"; $Return = passthru("$Command"); echo "\n\n----Returns----\n"; echo "$Return"; echo "\n\n\n\n=========================================================\n"; echo "SYSTEM()=================================================\n"; $Return = system("$Command"); echo "\n\n----Returns----\n"; echo "$Return"; ?> -- PHP scripts that make your job easier http://www.analysisandsolutions.com/code/ SQL Solution | Layout Solution | Form Solution T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y 4015 7 Ave, Brooklyn NY 11232 v: 718-854-0335 f: 718-854-0409
