Formatting text in upper case - upper case

Question

I am building an application using PHP and I am beginner in systems development. How do I format the text fields for all uppercase letters?

Answer 1

This is done with CSS:

div {
    text-transform: uppercase;
}

If you really want to do it in PHP you can use strtoupper for ISO-8859-1 and mb_strtoupper for UTF8

echo strtoupper('Texto'); // dá TEXTO

Answer 2

Carlos, the formatting of text is proper FRONT-END language, like html, css, javascript and others, in PHP the function of string strtoupper($text) can help you, but the most correct way is up to CSS with the argument 'font-Variant' bringing something like 'small-caps', you can have a class that returns all the text in versalete for example.

You can have the same effect in javascript:

getElementByTagName("INPUT").style.fontVariant="small-caps";

<input type="text" value="default text" class="versalete" />

in css:

.versalete{font-variant:small-caps;}
