Question

I have a java file and it will generate a report. I want to execute this within in a php script. Im using the exec() function in php:

<?php
$output = array();
$return  = 0;
exec("D:");
exec("cd class");
exec("java login username password id name Daily Detailed  20120820",$output,$return);
?>

When I execute this commands in windows command prompt it works properly. But not in a php script?

Answer 1

Try:

exec('"pushd d:\class & java login username password id name Daily Detailed 20120820"',$output,$return);)

The & is because you have multiple commands, and the context is not going to be remembered between exec’s.

Also, php exec calls cmd /c on your exec command, so you need an extra pair of quotes around the whole call.

(cmd /? from your command prompt explains more on /c).
