MYSQL入门之二_PHP操作MYSQL

1.        本地连接MySQL

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

              if(!$con) {

                     die('Could not connect: ' .mysql_error());

              }else {

                     echo"Connect success <br/>\n";

              }

2.        SAE连接MySQL

              $con =mysql_connect(SAE_MYSQL_HOST_M.':'.SAE_MYSQL_PORT,

                            SAE_MYSQL_USER,SAE_MYSQL_PASS);

              if (!$con) {

                     die('Could not connect: ' .mysql_error());

              } else {

                     echo"Connect success <br/>\n";

              }

              mysql_select_db(SAE_MYSQL_DB,$con);

3.        断开MySQL

              mysql_close($con);

4.        建立数据库

              $sql = "CREATE DATABASE IFNOT EXISTS $DATABASE_NAME";

              if(mysql_query($sql, $con)) {

                     echo "Database create success<br/>\n";

              }else {

                     echo"Error creating database: " . mysql_error() ."<br/>\n";

              }

5.        连接使用数据库

              mysql_select_db($DATABASE_NAME,$con);

6.        建立数据表

              $sql ="CREATE TABLE $TABLE_NAME (

                     namevarchar(80),

                     ageint

              )ENGINE=MyISAM DEFAULT CHARSET=utf8";

              if(mysql_query($sql,$con)) {

                     echo "Table create success<br/>\n";

              }else {

                     echo"Error creating table: " . mysql_error() . "<br/>\n";

              }

7.        查找数据

              $sql= "SELECT * FROM $TABLE_NAME where name like \"%$INPUT%\"";

              $result= mysql_query($sql,$con);

              while($row =mysql_fetch_array($result)) {

                     echo$row['name'] . " " . $row['age'];

                     echo"<br/>";

              }

8.        设置字符集（设置之后的sql操作基于utf8字符集）
mysql_query("SET NAMES 'utf8'");
mysql_query("SET CHARACTER_SET_CLIENT=utf8");
mysql_query("SET CHARACTER_SET_RESULTS=utf8");
