Hello Friends Today, through this tutorial, I will tell you How do you convert a string to uppercase using PHP, PHP 8, PHP 8.1, PHP 8.2, PHP 8.3 With Example. In PHP 8 & 8.1, you can convert a string to uppercase using the `mb_strtoupper()` function, which supports multi-byte character encoding. Here’s how you can use it:
<?php // Original string $string = "Hello, World!"; // Convert the string to uppercase $uppercase_string = mb_strtoupper($string); // Output the uppercase string echo $uppercase_string; ?>
In this example, `mb_strtoupper()` function is applied to the original string, converting all characters to uppercase. The resulting uppercase string is then stored in the variable `$uppercase_string` and echoed out.
The output will be:
HELLO, WORLD!
This function is particularly useful when working with strings that contain multibyte characters, such as those in UTF-8 encoding. If you’re working with single-byte character encoding like ASCII, you can use the `strtoupper()` function, which does not require the `mbstring` extension.
