<?php $result
= mysql_query( $sql ); while ( $row
= mysql_fetch_array( $result )) { ?> 要写的内容代码,比如说Html <?php } ?> |
可以在html中添加数据提交到数据库中,前提要和数据库中名字信息一致
表单提交:
1 |
<form action= "showDaYin.php"
method= "post" ><br> .......<br> <input type= "submit"
name= "submit"
value= "添加" ><br></form> |
这是一部分提交表单中的数据的代码,其中包含有链接到数据库的

<html> <head> <title>添加信息</title> <meta http-equiv= "Content-Type"
content= "text/html;charset=UTF-8" /> </head> <body> <?php if (@ $_POST [ ‘submit‘ ]){ $id

"年龄:" . $age . "<br/>" ; echo

"爱好:" . $fav . "<br/>" ; $conn
= mysql_connect( "localhost" , "root" , "" ) or
die ( "数据库连接失败!!" ); <span style= "color: rgb(204, 153, 255);" > //找到mysql服务器</span> mysql_select_db( "test" ); <span style= "color: rgb(204, 153, 255);" > //选择链接到的数据库</span> mysql_query( "set names ‘utf8‘" ); <span style= "color: rgb(204, 153, 255);" > //设置编码</span> $sql
= "INSERT INTO `test`.`students`(`id`, `names`, `address`, `age`, `sex`, `hobby`)VALUES (null,‘$name‘,‘$address‘,$age,‘$sex‘,‘$fav‘)" ; mysql_query( $sql ) or
die (mysql_error()); <span style= "color: rgb(204, 153, 255);" > //执行数据库操作</span> mysql_close( $conn ); } ?> </body> </html> |
只能读出返回运行一次的值:
1
2 |
$result
= mysql_query( $sql ); $row = mysql_fetch_array( $result ) |
要显示库中所有数据需要加上循环

<?php $result
= mysql_query( $sql ); while ( $row
= mysql_fetch_array( $result )){ ?> //内容代码 <?php } ?> |
