本文主要和大家分享php和mysql创建数据表及获取内容渲染到前端页面的方法，希望能帮助到大家。
1. mysql命令行创建数据表（表结构）：
源码：
create table myValues( id int(4) not null primary key auto_increment, name char(20) not null, year int(20) not null, sex char(20) not null, class char(20) not null, degree double(16,2) );
2. mysql命令行查看表结构：

3.php连接mysqli数据库
$connect = mysqli_connect('localhost','root','root'); //连接数据库
if($connect){
echo '连接数据库成功！';
}else{
echo '连接数据库失败';
}
//连接数据表
mysqli_select_db($connect,'lgc');4. php向数据库插入数据
//向数据库发送操作信息 mysqli_query($connect,'set names utf8'); mysqli_query($connect,'insert into myvalues values(1,"王二",20,"男","13.1班","98.68")'); mysqli_query($connect,'insert into myvalues values(2,"李三",22,"男","12.5班","88.66")'); mysqli_query($connect,'insert into myvalues values(3,"小花",16,"女","13.1班","78.32")'); mysqli_query($connect,'insert into myvalues values(4,"小明",15,"男","12.6班","69.95")'); mysqli_query($connect,'insert into myvalues values(5,"小刚",18,"男","13.2班","83.75")'); mysqli_query($connect,'insert into myvalues values(6,"小贝",23,"女","12.3班","93.63")');
5. php向数据库发送查询信息
//像数据库提交查询信息(所有信息) 返回查询到资源句柄 $info = mysqli_query($connect,'select * from myvalues');
6.php获取在数据库中查询到数据：（重要）
$newArr = array();
while($arry = mysqli_fetch_array($info,MYSQLI_ASSOC))
{
array_push($newArr,$arry);
}
exit(json_encode($newArr));
//获取数据：
//Array ( [0] => Array ( [id] => 1 [name] => 王二 [year] => 20 [sex] => 男 [class] => 13.1班 [degree] => 98.68 ) [1] => Array ( [id] => 2 [name] => 李三 [year] => 22 [sex] => 男 [class] => 12.5班 [degree] => 88.66 ) [2] => Array ( [id] => 3 [name] => 小花 [year] => 16 [sex] => 女 [class] => 13.1班 [degree] => 78.32 ) [3] => Array ( [id] => 4 [name] => 小明 [year] => 15 [sex] => 男 [class] => 12.6班 [degree] => 69.95 ) [4] => Array ( [id] => 5 [name] => 小刚 [year] => 18 [sex] => 男 [class] => 13.2班 [degree] => 83.75 ) [5] => Array ( [id] => 6 [name] => 小贝 [year] => 23 [sex] => 女 [class] => 12.3班 [degree] => 93.63 ) )
//json_encode()之后：
[{"id":"1","name":"\u738b\u4e8c","year":"20","sex":"\u7537","class":"13.1\u73ed","degree":"98.68"},{"id":"2","name":"\u674e\u4e09","year":"22","sex":"\u7537","class":"12.5\u73ed","degree":"88.66"},{"id":"3","name":"\u5c0f\u82b1","year":"16","sex":"\u5973","class":"13.1\u73ed","degree":"78.32"},{"id":"4","name":"\u5c0f\u660e","year":"15","sex":"\u7537","class":"12.6\u73ed","degree":"69.95"},{"id":"5","name":"\u5c0f\u521a","year":"18","sex":"\u7537","class":"13.2\u73ed","degree":"83.75"},{"id":"6","name":"\u5c0f\u8d1d","year":"23","sex":"\u5973","class":"12.3\u73ed","degree":"93.63"}]7. ajax加载数据:
