   Got a question: If I reload I expect everything to be reset but for some reason it keeps the value I last echo'd. What's up with that?

   Why it doesn't work?
   <?php
   //upper / lower case conversion
   if(isset($_GET['user_name'])&&!empty($GET['user_name'])){
   $user_name = $_GET['user_name'];
   $user_name_lc = strtolower($user_name);
   if($user_name_lc == 'alex'){
   echo 'You are the best';
   }

   ?>

   <form action="index.php" method="GET">
   Name: <input type="text" name="user_name" ><br><br>
   <input type="submit" value="Submit!" >
   </form>

   This is not a beginner tutorial at all. I'm lucky I'm watching this as a refresher, but I would really be confused as a beginner.

   Its best to have google handy and do research about those codes that haven't been taught. Or just go to parts 69 and 71.

   For those who are confused, go and watch Parts 69 to 71 to learn about $_GET, $_POST and <form>. I do find it silly that he just jumped right into this before even teaching about it.

    I'm lost on this one. Why isn't strtolower working? It echoes aLeX when you enter aLeX…I thought the point of strtolower was to change all characters to lower case. Confused.

    correct me if i'm wrong

    isset function is a function that checks if the string is set and not null
    empty function simply checks if the string is empty
    these two functions was used to for checking purposes so we won't have any error when getting a input from the user.

    now there are two methods of getting inputs from the user
    $GET – shows the input in the address bar
    $POST – doesn't show the input in the address bar

    he sets an action for the form "index.php" > this is where the web will take you when you clicked the submit button, or simply where the action will take place

    he sets the method as GET > he used this so we can tell if the input is really that input we gave to the textbox

    he sets the name of the textbox as "user_name" > so it will have a unique id and if we ever want to get the input from that textbox we can use ["user_name"]

    isset($_GET["user_name"]) > this checks the input that we got using GET method (you can check the input in the address bar) if it is a set or not null

    !empty($_GET["user_name]) > checks if the input is not empty

    $_GET["user_name"] is simply equal to what we have inputted in the textbox

    i guessed that he didn't explained the whole function and each statements cause it will make the video longer and he just want to show how we can use the lower case conversion

    If you were not concerned about keeping the original structure of the user typed username.You could avoid making a second variable and the extra line of code and simply do the following: 
    $user_name = strtolower($_GET['user_name']);

    Lots of people confused about isset also.
    The isset() function is only checking that the variable inside it has been defined and "is set" that is all.

    <?php

    $string = 'I Could Be Any C$$$ase.';

    $string_lower = strtolower($string);
    $string_upper = strtoupper($string);

    echo $string_lower;
    echo $string_upper;
    ?>
