我有一个包含3个表的数据库，每个表有6到20行，但我的PHP代码创建了8个表，当时应该只有2个（数据库中有2个帖子）
但为什么会这样做，我从不同的PHP页面获取代码，它在哪里工作正常？
<?php
session_start();
require_once("connect.php");

答案 0 :(得分：0)
如果您将查询分成几个部分，以便第一个查询从一个表中选择*并且下一个查询选择数据，则另一个表然后通过mysql_fetch_array($query1, $query2)
答案 1 :(得分：0)
按照此示例使用您的数据信任我它将起作用
// set up your query within a variable to make it easier to work with
$query = "SELECT * FROM people";
$result = mysql_query($query); //this will conect to the database and select the table to run the query on and return the values from that table.
// now we will set up a while loop to retrieve the information from the database table.
while ($person = mysql_fetch_array($result)) {
echo "<h3>". $person['name'] ."</h3>"; // this line will fetch the query result that is stored in the $person variable and find the row ['name'] and display it on screen
echo "<p>". $person['info'] ."</p>";
}
