我创建了一个函数来从数据库中获取数据，但它不起作用我不知道出了什么问题这是代码：
<?php
function Connect_Show($server_name,$server_user,$server_pass,$db,$db_table){
$connect = mysql_connect($server_name,$server_user,$server_pass) or die ('error , can not connect to database ') ;
$select = mysql_Select_db($db) or die (' error , can not select the database ');
$query = mysql_query("SELECT * FROM $db_table order by id ")
while ($rows = mysql_fetch_assoc($query)) {
echo $rows['id'];
echo $rows['name'];
echo $rows['emails'];
echo $rows['password'];
}}
echo Connect_Show("localhost","root","root","learn","users");
?>
而不是
echo Connect_Show("localhost","root","root","learn","users");
只需使用这个：
Connect_Show("localhost","root","root","learn","users");
Connect_Show is a function, with echo commands in it, its not returning anything.
