?>We can change all characters to lower case by using strtolower. The following code is an example.
<?php
$string = 'I am ThEt NainG WiN!';
$string_low = strtolower($string);
echo $string_low;

We can also change all characters to upper case by using strtoupper. The following is an example.
<?php
$string = 'I am ThEt NAInG win!';
$string_up = strtoupper($string);
echo $string_up;
?><?php

Write the following code and save it as info.php in C > xampp > htdoc.
<?php
phpinfo();

Open Web Browser and type localhost/info.php in it and press Enter. Then, you will see the php version as the below picture.
We need Apache Service to run php codes. Now I hope you've already installed the Apache Service in your Windows PC. If you have not installed, please click here.
We need Text Editor to write php codes. If you don't have any text Editor, please click here.
If you've completed the above steps. We will start to write php codes.
1. Open your Text Editor (here I use ConText) and create New File.
2. Choose PHP instead of Text files as the below picture.
3. Save that file as test.php in the C > xampp > htdoc.
4. In test.php, write the following codes.
