Fetching Chinese Text from Database to Web in UTF-8

This section describes how to fetch Chinese text from MySQL database and send it to a Web page through Apache in UTF-8 encoding.

To fix the problem I had in the previous test, I decided to:

Here is the new test PHP script that changes MySQL and HTML document settings to display Chinese characters in UTF-8 encoding:

#- MySQL-Web-Chinese-UTF8.php
#- Copyright (c) 2015, HerongYang.com, All Rights Reserved.
  $con = mysql_connect("localhost", "Herong", "TopSecret");
  $ok = mysql_select_db("HerongDB", $con);
  $test_name = "Moving Chinese Text from Database to Web";
  print('<meta http-equiv="Content-Type"'.
    ' content="text/html; charset=utf-8"/>');

# Delete the record
  $sql = "DELETE FROM Comment_Mixed WHERE Test_Name ='$test_name'";
  mysql_query($sql, $con);
  print("\nNumber of rows deleted: ".mysql_affected_rows()."\n");

# Build the SQL INSERT statement
  $sql = <<<END_OF_MESSAGE
INSERT INTO Comment_Mixed (Test_name, String_ASCII, 
    String_Latin1, String_UTF8, String_GBK, String_Big5)
  VALUES ('$test_name', 'Television', 
  mysql_query($sql, $con);
  print("\nNumber of rows inserted: ".mysql_affected_rows()."\n");

# Set character_set_results
  mysql_query("SET character_set_results=utf8", $con);

# Fetch text data from database
  $sql = "SELECT * FROM Comment_Mixed"
    . " WHERE Test_Name = '$test_name'";
  $res = mysql_query($sql, $con);

# Send text data output
  if ($row = mysql_fetch_array($res)) {
    print("\nTest Name = ".$row['Test_Name']."\n");
    print("   String_ASCII: ".$row['String_ASCII']."\n");
    print("   String_Latin1: ".$row['String_Latin1']."\n");
    print("   String_UTF8: ".$row['String_UTF8']."\n");
    print("   String_GBK: ".$row['String_GBK']."\n");
    print("   String_Big5: ".$row['String_Big5']."\n");


Now the output is perfect. Chinese characters stored in UTF-8, GBK(GB2312) and Big5 are all correctly displayed on the Web page:
Displaying Chinese correctly in UTF-8

If you are surprised by the fact that Chinese characters in GBK and Big5 encodings are also displayed correctly on a Web page with charset=utf-8, read this explanation:

MySQL did a good job on converting my GBK and Big5 encoded characters to UTF-8 encoded characters. I am impressed!
