get system boot time in minutes in php

You can use the shell_exec function in PHP to execute a command on the system and retrieve the output. On Linux systems, you can use the uptime command to get the system uptime, which includes the time the system was booted.

Here's an example PHP code snippet that retrieves the system uptime and calculates the boot time in minutes:

main.php
$uptime = shell_exec('uptime -s');
$boot_time = strtotime($uptime);
$minutes_since_boot = (time() - $boot_time) / 60;

echo "System booted {$minutes_since_boot} minutes ago.";
176 chars
6 lines

The uptime command with the -s option returns the system boot time in ISO 8601 format. The strtotime function converts the boot time string to a Unix timestamp, which represents the number of seconds since the Unix Epoch (January 1 1970 00:00:00 UTC). Finally, we calculate the number of minutes since the boot time by dividing the difference between the current time and the boot time by 60.
