php_uname() : information about the operating system PHP is running on

Read operating-system information with php_uname()

php_uname() returns information about the operating system that is running PHP. PHP_OS_FAMILY and PHP_OS are often enough when code only needs to identify the platform family.

<?php
echo php_uname('s') . PHP_EOL;
echo PHP_OS_FAMILY;
?>

We can get information about the operating system , host name, release name, version information and machine type by using php_uname() function. Here is the simple command

<?Php
<br>echo php_uname();
<br>
?>

The output is here
