PHP的MySQL配置

報(bào)錯(cuò)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";",

同時(shí)在下面增加extension=php_mysqli.dll;

注意后面那個(gè)dll多了個(gè)i
2."/extension_dir"檢查路徑是否正確;
3.找到ext/目錄,把其中的php_mysql.dll,php_mysqli.dll兩個(gè)文件Copy to %systemroot%/system32下.
4.重啟服務(wù)

連接數(shù)據(jù)庫(kù)
?//在conf/php.ini中,在vim用"/php_mysql"搜索到extension=php_mysql.dll,去掉前面的";",同時(shí)在下面增加extension=php_mysqli.dll;
$mysqli = new mysqli("127.0.0.1","用戶(hù)名", 密碼","庫(kù)名");
$query="select * from??表 order by theindex desc";
$mysqli->query("SET NAMES gb2312");//注意此處不加會(huì)亂碼
$result = $mysqli->query($query);

?//printf() 函數(shù)輸出格式化的字符串
while(list($name, $theindex) = $result->fetch_row())
??????? echo(" <br />".$name.$theindex);

$con = mysql_connect("localhost", "用戶(hù)名", "密碼");
if ($con) {
??????? mysql_query("set names 'gb2312'");
??????? mysql_select_db("庫(kù)名", $con);//注意此處不加會(huì)亂碼
??????????????????????????????? $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);
}
