PHP: Method, Class, Uppercase.

[jacob1986]

I have to write small segment of PHP code to print the word(s) 'Hello, World!' in uppercase letters, I have thus far wrote a small section of code that prints the output 'Hello, World!'. But, I'm completely stuck on how to make the letters all uppercase?!?? Moreover; that strtoupper goes somewhere in there right?

 

<?php

class TextFunctions {
    public static $string = 'Hello, World!';
    static public function strtoupper() {
        
    }
}

echo TextFunctions::$string;

?>

strtoupper() is a function that already exists. You don't make it yourself.

It takes a string as an argument and returns a string. What it returns is uppercased.

 

echo strtoupper(TextFunctions::$string);

You can also do this via CSS with text_transform: uppercase.

That will only affect the display in the form, not convert. Lowercase characters are posted EG

<?php 
if ($_SERVER['REQUEST_METHOD']=='POST')
    echo "Posted value : {$_POST['test']}";     //--> Hello World

?>
<form method='post'>
<input type='text' name='test'   style='text-transform:uppercase' value='Hello World'>
<input type='submit' name='btnsub' value='Submit'>
</form>

Barand - absolutely, but if using CSS to modify the display is appropriate and allowed for the assignment, it's another viable way to do it.
