PHP項目出現亂碼，緣由就是軟件之間，模板之間的編碼有差別，不相同：javascript

新建".html", ".php" , ".tpl" , ."js" , ".css"等文件使用utf8統一的編碼格式；
在開發工具中設置默認新建文件時的編碼格式；
mysql_query("set character set 'utf8'"); //讀庫php
mysql_query("set names 'utf8'"); //寫庫css
default-character-set=utf8 //MySQL配置文件"my.ini"編碼設置
init-connect=\'SET NAMES utf8\' //MySQL配置文件"my.ini"編碼設置
collation_server=utf8_unicode_ci //MySQL配置文件"my.ini"編碼設置
character_set_server=utf8 //MySQL配置文件"my.ini"編碼設置
default_charset = "UTF-8" //php配置文件"php.ini"編碼設置
header('Content-type:text/html;charset=utf-8'); //php 文件輸出頭
header("Cache-Control:no-cache"); //php文件輸出頭
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> //html頁面中使用的編碼html
在phpMyAdmin中修改mysql中數據庫，數據表及數據字段的字符編碼格式； //編碼設爲：utf8_general_ci
數據庫執行語句：CREATE DATABASE `dbname` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
<script type="text/javascript" src="*****.js" charset="utf-8"></script> ---在js引入時加入
待續...

示例代碼1：
$mysqli=new mysqli("localhost", "mysql_user", "mysql_pwd", "mydb"); //創建mysqli對象
     //執行SQL語句從用戶表User中查詢全部記錄，保存在$User數組中
$mysqli->query("set names gb2312");
if($result=$mysqli->query("SELECT id, name, sex, age, email FROM User")){
  while($row=$result->fetch_assoc()){                //循環從結果集中遍歷每行數據
   $users[]=$row;                             //取出全部行都保存在同一個數組中
  }
  $rowNum=$result->num_rows;                    //將獲取的數據行數保存在變量中
  $result->close();                                 //關閉結果集
}
$mysqli->close(); java

示例代碼2：mysql

<?php 

$charset = "utf8";

$con = mysql_connect("localhost", "root", "");

mysql_query("SET character_set_connection=$charset, character_set_results=$charset, character_set_client=binary", $con);

mysql_select_db("ecshop", $con);

$sql = "SELECT user_name, email FROM ecs_admin_user WHERE user_id = 4";
$result = mysql_query($sql, $con);
$array = mysql_fetch_array($result, MYSQL_ASSOC);
mysql_close($con);

$name = $array["user_name"];
$email = $array["email"];

?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>

<h1>你好, <?php echo $name; ?>!</h1>
<h2>你的郵件是：<a href="mailto:<?php echo $email; ?>"><?php echo $email; ?></a></h2>

</body>
</html>
