php mysqli多个查询
mysqli多个查询
mysqli_multi_query(mysqli link,string query)连续执行多次查询，是基于过程的
msyqli_more_results(mysqli link)主要确定返回的结果集是否有其他的结果集
mysqli_next_result(mysqli link)获取下一个结果集
示例：
<?php
#连接数据库
$link=mysqli_connect("localhost","root","root");
#选择数据库
$link->select_db("rorely") or die("could not find database");
#查询数据库
if($link->multi_query("select * from test;select name ,age ,sex,address from test")){
do{
$result=$link->store_result();
while($row=$result->fetch_row()){
echo "$row[0],$row[1],$row[2],$row[3]<br>";
}
if($link->more_results()) echo "**********<br>";
}while($link->next_result());
}
$link->close();
?>
结果如下：
1,Jane,26,female
3,Tome,21,male
4,Lily,25,female
5,Lucy,25,female
