$_POST is when your form method is post.

$_GET is when your form method is get.

 

All variables are confined to a function if they are created in one, unless you use global to change it from a local variable (in one function) to a global variable (used in the whole script).

 

<?php
function localVar(){
   $localvar = "local";
   echo "localVar : " . $localvar;
   echo "<br />";
}
function globalVar(){
   global $globalvar;
   $globalvar = "global";
   echo "globalVar : " . $globalvar;
   echo "<br />";
}
localVar();
globalVar();
echo $globalvar . " | " . $localvar;
?>

 

outputs

 

localVar : local

globalVar : global

global |
