include("config.php");
$global_dbh = mysql_connect($hostname, $username, $password)
or die("Could not connect to database");
mysql_select_db($db)
or die("Could not select database");
function display_db_query($query_string, $connection, $header_bool, $table_params) {
// perform the database query
$result_id = mysql_query($query_string, $connection)
or die("display_db_query:" . mysql_error());
// find out the number of columns in result
$column_count = mysql_num_fields($result_id)
or die("display_db_query:" . mysql_error());
// Here the table attributes from the $table_params variable are added
print("<TABLE $table_params >\n");
// optionally print a bold header at top of table
if($header_bool) {
print("<TR>");
for($column_num = 0; $column_num < $column_count; $column_num++) {
$field_name = mysql_field_name($result_id, $column_num);
print("<TH>$field_name</TH>");
}
print("</TR>\n");

推荐答案
要始终获得正确编码的UTF-8文本的四个好步骤:
1)先运行此查询，再执行其他任何查询:
1) Run this query before any other query:
mysql_query("set names 'utf8'");
2)将此添加到您的HTML头中:
2) Add this to your HTML head:
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
3)在您的PHP代码顶部添加此代码:
3) Add this at top of your PHP code:
header("Content-Type: text/html;charset=UTF-8");
4)使用 Notepad ++ 或其他任何出色的文本编辑器，以UTF-8 without BOM编码保存文件/IDE.
4) Save your file with UTF-8 without BOM encoding using Notepad++ or any other good text-editor / IDE.
