Batch file run using PHP works but only displays last line

I have a batch file that displays a list of registry keys.

10000 20000 30000 40000 ..etc.

Using PHP, I can display the output of the batch file:

echo exec('file.bat');

This only shows me 40000 though, not the other three entries. How can I see every开发者_运维百科thing?

Use shell_exec() instead.

exec() returns the last line from STDOUT. You can pass a second parameter to capture all of the STDOUT.

exec($command, $output = array());

Then all of the output text will be in $output.
