Does it do a pair of weeks it was entrusted to me to migrate a place (developed in php) of servant, the topic was going relatively in peace until I realized of a problem appellant in this type of situations, the ancient servant had the global variables in On and did the new one them have in Off... appellant not?

Is the truth that I did not want to complicate the life like other times, and I realized something that might save a pair of working time, all the php were doing an include to a file php, appellant also not?
Like that is that I started thinking about a piece of code that should me to take these 3 types of variables (SESSION, POST AND GET) and it will leave them to me like normal variables, if they it do not realize well the exercise it is more or less the following one:

Let's suppose that the variable comes from a form route POST, the code was saying something like that...

<?

if ($variable = "a little")
{
   I begin "this variable does some thing";
}

?>

Namely he was lacking this instruction before the if

<? php

$variable = $_POST ["variable"];//he was lacking this instruction before the if

if ($variable = "a little")
{
   I begin "this variable does some thing";
}

?>

It had 2 options, or was starting looking for ALL these situations and one was arranging them to one, or it was placing a code piece in file to which all the rest were making him an include who was correcting this proper "error" of those that we are to be employed with the "servants at production", or, with the global variables in On.

Very well, after many blending me I found the solution, and here I show it to all uds.

<?

if ($_POST)
{
   $keys_post = array_keys ($_POST);
   foreach ($keys_post grasp $key_post)
     {
      $$key_post = $_POST [$key_post];
      error_log ("variable $key_post comes from $ _POST");
     }
}

if ($_GET)
{
   $keys_get = array_keys ($_GET);
   foreach ($keys_get grasp $key_get)
     {
        $$key_get = $_GET [$key_get];
        error_log ("variable $key_get comes from $ _GET");
     }
}

if ($_SESSION)
{
   $keys_sesion = array_keys ($_SESSION);
   foreach ($keys_sesion grasp $key_sesion)
     {
       $$key_sesion = $_SESSION [$key_sesion];
       error_log ("variable $key_sesion comes from $ _SESSION");
     }
}

?>

There are basically 3 if that do the same, they take the keys of the arrangement in question (SESSION, POST or GET) and generate a "variable variable", I believe that there is an article in desarrolloweb that speaks about this topic, and this does the whole magic, error_log was an implementation to see that variables were dealing (if you do not have access to the servant you can extract it without problems).

For someone who likes the functions he can keep it also like function and call it when he needs it. Or also to iterate the process with 3 variables in question not to have to do 3 if, or spend any arrangement to him so that it does the same process... anyway, the this idea, only I hope to have contributed in something to the saving of time of some of you.
