iconv_set_encoding - PHP code example

PHP Function Iconv_Set_Encoding

php function iconv_set_encoding is an inbuilt php function which helps in setting the current character encoding conversion. It takes two parameters – $type and $encoding. If you append the string //TRANSLIT to the to_encoding string then transliteration is activated which means that characters that cannot be represented in the target encoding can be approximated through one or more similarly looking characters. If you do not append the string //TRANSLIT, then when a character cannot be represented in the to_encoding, an E_NOTICE will be generated and the function returns FALSE.

This function works with the help of output buffering. This is a mechanism that allows the PHP engine to store all the data for execution and render it before it gets sent to the browser. This will help in increasing the efficiency and feasibility of the script as it decreases the number of interactions between the engine and the browser.

This php function is available on all the POSIX compliant systems but to make use of it you will need libiconv library to be installed on your system. You can download this from here. Using this function and a few more inbuilt php functions will enable you to create and manipulate html files efficiently in your web application. We have provided some php examples at the top of this article to practice the syntax of this language. Please check them out and try to implement the same in your own application.
