php iconv mb_convert_encoding encoding conversion function_PHP tutorial

Use the iconv function:

iconv( "utf-8", "gb2312" , "abc sunshine 123");

It is said that this is better, and you can ignore the errors during conversion!

iconv( "utf-8", "gb2312//ignore" , "abc sunshine 123");

For the usage of mb_convert_encoding, please see the official website:
http://cn.phptutorial.net/manual/zh/function.mb-convert-encoding.php

Make a gbk to utf-8

< ?php
header("content-type: text/html; charset=utf-8");
echo mb_convert_encoding("My friend", "utf-8", "gbk");
?>

One more gb2312 to big5

< ?php
header("content-type: text/html; charset=big5");
echo mb_convert_encoding("You are my friend", "big5", "gb2312");
?>

However, to use the above function, you need to install and enable the mbstring extension library first.

Another function iconv in php is also used to convert string encoding, and its function is similar to the function above.

There are some detailed examples below:
iconv — convert string to requested character encoding
(php 4 >= 4.0.5, php 5)
mb_convert_encoding — convert character encoding
(php 4 >= 4.0.6, php 5)

Usage:
string mb_convert_encoding ( string str, string to_encoding [, mixed from_encoding] )
You need to enable the mbstring extension library first, and remove the ; in front of extension=php_mbstring.dll in php.ini
mb_convert_encoding can specify multiple input encodings, which will be automatically identified based on the content, but the execution efficiency is much worse than iconv;
