isPostBack()

Today's function comes not from PHP, but ASP.NET. We're going to replicate the isPostBack() function from ASP.NET's Page object.

ASP

1. function isPostBack()
2.     if uCase(Request.ServerVariables("REQUEST_METHOD")) = "POST" then
3.         isPostBack = true
4.     else
5.         isPostBack = false
6.     end if
7. end function

PHP

1. function isPostBack()
2. {
3.     return ($_SERVER['REQUEST_METHOD'] == 'POST');
4. }
