[SOLVED] Need to execture a BATCH file

[tyler6699]

I have this code:

 

exec('start /B "window_name" "start_pc.bat"',$output,$return);

 

This will run the batch file and works fine but, I want to replace "start_pc.bat" with a variable

 

How can I execute this:

 

$filename = ("$user ("$user" . ".bat" );

exec('start /B "window_name" "$filename"',$output,$return);

 

Have tried: exec, system and many other ways to execute the file also tried '$filename' but did not work

 

any help will be appreciated as Ive tried for two days to get this working

 

thanks

excuse the bad spelling

 

think i meant this

 

$filename = ("$user" . ".bat" );

 

sorry

<?php

$user = "test";

$f = "start /B \"window\" \"$user.bat\"";

 

echo exec($f);

 

?>

 

this will execute a batch file named "test.bat"
