将STDOUT（Bash）传递给PHP变量

Question

I want to pass the stdout of a command in bash (ex. uptime) to a PHP variable, let's say uptime too. How this can be done?

Answer 1

Use shell_exec for returning the output of shell commands:

<?php
    $output = shell_exec('uptime');
    echo $output;
?>

Result:

18:17  up 12 days, 13:39, 3 users, load averages: 1.80 1.78 1.75
