mb_language - PHP code example

Using the MB_Language Function in PHP

PHP is a server-side scripting language that allows you to build web applications and websites. It has more than 1000 built-in functions that allow you to perform specific tasks in your code. PHP functions can be used to perform operations on data, like converting from one character set to another or performing mathematical calculations. They can also be used to pass information from one part of your code to another. Functions are executed by calling them with a name and any parameters you want to pass to it. These arguments are specified right after the function name inside parenthesis. The information that is passed to the function is stored in a variable. The function itself can then use the value of that variable in its own logic.

The mb_language function is used for encoding email messages. It sets the language of an e-mail message based on a string. The valid languages are "Japanese", "ja","English","en" and "uni" (UTF-8). mb_send_mail() uses this setting to encode the e-mail message. If the parameter is omitted, it returns current language as string.

Note: this function is EXPERIMENTAL. Its behaviour might change in a future release without notice. So, it is better to use this function with care.
