Archived: Sending Text in UTF8 Encoding to MySQL 5
This section provides a test on sending non-ASCII character strings to MySQL 5 server in UTF8 encoding.
The next test I did was to re-run the same SQL INSERT statement that included Latin1, UTF-8, GBK and Big5 characters directly. But I changed MySQL session settings with character_set_client=utf8 and character_set_connection=utf8 to see how MySQL 5 applies the conversion when executing the INSERT statement.

$con = mysql_connect("localhost", "Herong", "TopSecret");
$ok = mysql_select_db("HerongDB", $con);
$test_name = "Send Non-ASCII";
# Set character_set_results
mysql_query("SET character_set_results=utf8", $con);
# Set character_set_client and character_set_connection
mysql_query("SET character_set_client=utf8", $con);
mysql_query("SET character_set_connection=utf8", $con);

print($row['Variable_name']." = ".$row['Value']."\n");
}
mysql_free_result($res);

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

INSERT INTO Comment_Mixed (Test_name, String_ASCII,
String_Latin1, String_UTF8, String_GBK, String_Big5)
VALUES ('$test_name', 'Television',
'T?l?vision', '电视机/電視機', '???', '???');
END_OF_MESSAGE;

print(mysql_errno($con).": ".mysql_error($con)."\n");
}
# Get the recode back
$sql = "SELECT * FROM Comment_Mixed"
. " WHERE Test_Name = '$test_name'";
$res = mysql_query($sql, $con);
if ($row = mysql_fetch_array($res)) {
print("\nTest Name = ".$row['Test_Name']."\n");
print(" String_ASCII: 0x".bin2hex($row['String_ASCII'])."\n");
print(" String_Latin1: 0x".bin2hex($row['String_Latin1'])."\n");
print(" String_UTF8: 0x".bin2hex($row['String_UTF8'])."\n");
print(" String_GBK: 0x".bin2hex($row['String_GBK'])."\n");
print(" String_Big5: 0x".bin2hex($row['String_Big5'])."\n");
}
mysql_free_result($res);
mysql_close($con);
?>
Note that string literals in the source code above will not be displayed properly, because this book uses UTF-8 encoding.
Here is the output with PHP 5 and MySQL 5:
C:\>\local\php\php MySQL-Send-Non-ASCII-UTF8.php character_set_client = utf8 character_set_connection = utf8 character_set_database = latin1 character_set_filesystem = binary character_set_results = utf8 character_set_server = latin1 character_set_system = utf8 character_sets_dir = \local\mysql\share\charsets\ Number of rows deleted: 0 Number of rows inserted: 1 Test Name = Send Non-ASCII String_ASCII: 0x54656c65766973696f6e String_Latin1: 0x543f6c3f766973696f6e String_UTF8: 0xe794b5e8a786e69cba2fe99bbbe8a696e6a99f String_GBK: 0x3f3f3f3f3f String_Big5: 0x3f713f3f3f3f
