1、使用php写一段简单查询,查出所有姓名为“张三”的内容并打印出来 表名User Name Tel Content Date 张三 13333663366 大专毕业 2006-10-11 张三 13612312331 本科毕业 2006-10-15 张四 021-55665566 中专毕业 2006-10-15 请根据上面的题目完成代码: $mysql_db=mysql_connect("local","root","pass"); @mysql_select_db("DB",$mysql_db);
代码
drop table if exists user; /*==============================================================*/ /* Table: user */ /*==============================================================*/ create table user ( `Name` varchar(20), Tel varchar(16), Content varchar(255), `Date` date ) insert into user(name,tel,content,`date`) values('张三','13333663366','大专毕业','2006-10-11'); insert into user(name,tel,content,`date`) values('张三','13612312331','本科毕业','2006-10-15'); insert into user(name,tel,content,`date`) values('张四','021-55665566','中专毕业','2006-10-1'); select * from user where name='张三';
代码
<?php header("content-type:text/html; charset=gbk"); $mysql_db=mysql_connect("localhost","root",""); @mysql_select_db("phpinterview",$mysql_db); echo "<table>"; mysql_query("set names gbk"); $result=mysql_query("select Name,Tel,Content,Date from user where Name='张三'") or die("错误:".mysql_error()); while($row=mysql_fetch_array($result,MYSQL_BOTH)) { echo "<tr><td>".$row["Name"]."</td><td>".$row["Tel"]."</td><td>". $row["Content"]."</td><td>".$row["Date"]."</td></tr>"; } mysql_free_result($result); echo "</table>" ?>
3、如何使用下面的类,并解释下面什么意思? class test{ function Get_test($num){ $num=md5(md5($num)."En"); return $num; } } <?php /** * 使用md5加密数据... * */ class test{ function Get_test($num){ $num=md5(md5($num)."En"); return $num; } } $a=new test(); echo $a->Get_test("123"); ?> 4、用javascipt打印 “上海爱吉” <html> <head><title>JS打印</title></head> <body> <script type="text/javascript"> document.write("上海吉它"); </script> </body> </html> 5、写出 SQL语句的格式 : 插入 ,更新 ,删除 代码
select expression from tablename where condition group by columns asc with rollup order by column asc limit offset,rowcount; insert into tablename(columname) values(exp); update tablename set columnname=exp where condition order by column limit rowcount; delete from tablename where condition order by column limit rowcount;
