Use php to execute shell command under linux to view the server's machine name_PHP tutorial

I came across a small need today.

How to display the server’s machine name in a web page,

In Ubuntu, just enter the command: uname -n to see (the same is true for Redhat),

So I wonder if php can directly call the shell command to perform this operation?

After checking the information,

I learned that there is indeed one, and there are several of them:

popen

fpassthru

shell_exec

exec

system

Read how to use it,

It seems that shell_exec is relatively simple. You only need to pass in the command as parameters,

And it directly returns the result after executing the command,

So I tried it:

< ?php

shell_exec('uname -n');

?>

Successfully displayed the machine name of the current server.

However, if it is a purchased server, the test may not be successful,

Because for security reasons, the server provider may disable some or all of them
