formating output from system()

[mediamind]

Hi All...

I'm making a script that will mail me the list of all users logged in the system.

$last = exec('last');

BUT how do i format the result?

if i use a for loop it only displays the last line. split up letter by letter

tryed some different things (nl2br, eregi_replace \n, etc...) nothing worked so far.

Regards,
Gerry.

from the manual:
exec() executes the given command, however it does not output anything. It simply returns the LAST LINE from the result of the command. If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

that was word for word... http://www.php.net/manual/en/function.exec.php

always check the manual first 🙂

use backticks (``) operator.

$last = last;
$last_list = explode('\n', $last);
