[PHP] - mysql 数据库操作

浏览数：27 / 时间：2015年06月12日

使用PHP操作数据库有两种方式

使用mysql_XXXX()方法
1. 使用这种方式，需要先把php.ini里的extension=php_mysql.dll去掉注释
使用PDO
1. 使用这种试，需要把php.ini里的extension=php_pdo_mysql.dll去掉注释

下面演示使用第一种方式：

<!doctype html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    </head>
    <body>
       <?php
           $conn = mysql_connect("localhost", "root", "zxbbugu");
           if(!$conn) {
               die("Could not connect:" . mysql_error());
           }
           
           mysql_select_db("test", $conn);
           //mysql_query("SET NAMES utf8");
           
           $result = mysql_query("INSERT INTO mytable(headline, create_time) VALUES(‘中国‘, ‘" . date("Y-m-d h:i:s") . "‘);");
           if( $result < 1) {
               echo "insert error!";
           }
           
           $query = mysql_query("SELECT * FROM mytable LIMIT 100 OFFSET 0;");
           while ($row = mysql_fetch_array($query, MYSQL_BOTH)) {
               echo "<p>", $row["id"], " - " , $row["headline"], " - ", $row["create_time"], "</p>";
           }
           
           mysql_close();
       ?>
    </body>
</html>

下面是使用PDO方式：

<!doctype html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    </head>
    <body>
       <?php
           $pdo = new PDO("mysql:host=localhost;dbname=test", "root", "zxbbugu");
           $stmt = $pdo->prepare(‘SELECT * FROM mytable WHERE id = :id‘);
           $stmt->execute(array(":id"=>1));
           foreach ($stmt as $row) {
               echo $row["headline"];
           }
           
           $result = $pdo->exec("INSERT INTO mytable(headline, create_time) VALUES(‘中国‘, ‘" . date("Y-m-d h:i:s") . "‘);");
           if($result) {
               $str = sprintf("add data completed, lastupdateid=%s", $pdo->lastInsertId());
               echo $str;
           }
           
           $rs = $pdo->query("SELECT * FROM mytable");
           while ($row = $rs->fetch()) {
               echo "<p>", $row["id"], " - " , $row["headline"], " - ", $row["create_time"], "</p>";
           }
       ?>
    </body>
</html>
