How to make UTF 8 PHP

"Learn how to set your PHP file to UTF-8 encoding with an example of adding this line to the top of a .php file: header('Content-Type: text/html; charset=utf-8');"

Using UTF-8 in PHP

UTF-8 is a widely used character encoding standard that supports almost all of the world's languages. It is widely used in web applications and software programs to represent characters and symbols from different languages and regions. In order to use UTF-8 in PHP, you need to set the appropriate encoding in the source code.

To do this, you can use the mb_internal_encoding() function. This function sets the default character encoding for all multi-byte string functions. It takes one parameter – the character encoding you want to use. For example, to set UTF-8 as the character encoding, you can use the following code:

mb_internal_encoding('UTF-8');

Once you have set the character encoding, you can start using the string functions for manipulating and displaying UTF-8 strings. For example, the mb_substr() function can be used to extract the first 10 characters from a UTF-8 string:

$str = 'Hello world!';
$substr = mb_substr($str, 0, 10);
echo $substr; // Outputs: Hello worl

Besides the mb_internal_encoding() function, there are several other functions that can be used to manipulate and display UTF-8 strings. For example, the mb_strlen() function can be used to get the length of a UTF-8 string:

$str = 'Hello world!';
$len = mb_strlen($str);
echo $len; // Outputs: 12

In addition to the string functions, there are also several other functions that can be used to work with UTF-8 strings. For example, the mb_detect_encoding() function can be used to detect the character encoding of a string:

$str = 'Hello world!';
$encoding = mb_detect_encoding($str);
echo $encoding; // Outputs: UTF-8

These are just a few of the functions that can be used to work with UTF-8 strings in PHP. There are many more, and it is important to understand how to use them in order to make sure that your web applications and software programs are able to handle UTF-8 strings correctly.
