Chinese Character String with UTF-8 Encoding

This section providing information on handling Chinese character string literals in UTF-8 encoding.

Since PHP strings are sequences of 8-bit characters, we can use them as binary strings to store Chinese character strings in UTF-8 encoding. In order to output Chinese characters to Web pages and display them correctly, you need to:

Here is a simple test I did on my local system:

1. Click Start > All Programs > Accessories > Notepad.

2. In Notepad, enter the following PHP script:

<?php 
#- String-UTF-8.php
#- Copyright (c) 2015, HerongYang.com, All Rights Reserved.
#
  $help_simplified = '这是一份非常简单的说明书…';
  $help_tradition = '這是一份非常簡單的說明書…';
  print('<html>');
  print('<meta http-equiv="Content-Type"'.
    ' content="text/html; charset=utf-8"/>');
  print('<body>');
  print('<b>Chinese string in UTF-8 in PHP</b><br/>');
  print($help_simplified.'<br/>');
  print($help_tradition.'<br/>');
  print('</body>');
  print('</html>');
?>

Note that I used some Chinese character input add-on tools to enter Chinese characters.

3. Select menu File > Save as. Enter the file name as String-UTF-8.php. Select "UTF-8" in the Encoding field and click the Save button.

4. Copy String-UTF-8.php to \local\apache\htdocs.

5. Now run Internet Explorer (IE) with http://localhost/String-UTF-8.php. You should see Chinese characters displayed correctly:
Chinese Web Page using UTF-8

This proves that the editor: notepad, the CGI program: PHP CGI, the Web server: Apache, and the Web browser: IE, all worked correctly with Chinese characters in UTF-8 encoding.
