PHP path_separator to determine the current server system type instance _php instance

There is a very useful predefined constant path_separator in PHP that we can use to determine whether the current server is Linux or Windows. This article will explain to you how PHP uses Path_separator to get the type of the current server.

Path_separator is a predefined constant in PHP, and we can directly echo this constant, in a Linux system, the constant output ":" In the Windows system, the constant output ";" Resolution Therefore, we can determine the current server system type by path_separator the output value.

Output results in Linux systems:

<?php
  var_dump (path_separator);
  Output Result: string (1) ":"
?>

To output results in a Windows system:

<?php
  var_dump (path_separator);
  Output Result: string (1) ";"
? >

Write a function that determines the current server system type:

function Getos () {
 if (Path_separator = = ': ') {return
 ' Linux ';
 } else{return
 ' Windows ';
 }

How you need to determine the current server system type, you can call the above function directly.
