PHP的MySQL配置

报错信息：Class \'mysqli\' not found in

Answer:
1.在conf/php.ini中,在vim用\"/php_mysql\"搜索到extension=php_mysql.dll,去掉前面的\";\",

同时在下面增加extension=php_mysqli.dll;

注意后面那个dll多了个i
2.\"/extension_dir\"检查路径是否正确;

3.找到ext/目录,把其中的php_mysql.dll,php_mysqli.dll两个文件Copy to %systemroot%/system32下.

4.重启服务

连接数据库

 //printf() 函数输出格式化的字符串
while(list($name, $theindex) = $result->fetch_row())
        echo(\" <br />\".$name.$theindex);

$con = mysql_connect(\"localhost\", \"用户名\", \"密码\");
if ($con) {
        mysql_query(\"set names \'gb2312\'\");
        mysql_select_db(\"库名\", $con);//注意此处不加会乱码
                                $rs = mysql_query(\"select * from  表 order by theindex desc;\", $con);
                                if ($rs) {
                                  echo (\"<table border=1>\");
                                        while($row = mysql_fetch_assoc($rs))
                                        {
                                                echo \"<tr>\" .
                                                \"<td>$row[theindex]</td>\" .
                                                \"<td>$row[name]</td>\" .
                                                \"</tr>\";
                                        }
                                        mysql_free_result($rs);
                                        }
                                        echo (\"</table>\");
        mysql_close($con);
}
