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 //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; $mysqli = new mysqli("127.0.0.1","用户名", 密码","库名"); $query="select * from 表 order by theindex desc"; $mysqli->query("SET NAMES gb2312");//注意此处不加会乱码 $result = $mysqli->query($query);
//printf() 函数输出格式化的字符串 while(list($name, $theindex) = $result->fetch_row()) echo(" ".$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 (""); while($row = mysql_fetch_assoc($rs)) { echo "" . "" . "" . ""; } mysql_free_result($rs); } echo (" $row[theindex] $row[name] "); mysql_close($con); }
