无法从数据库PHP

Question

我创建了一个函数从数据库中获取数据的数据，但它不工作，我不知道什么是错 这里是代码：

<?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"); 
?> 

Answer 1

而不是

echo Connect_Show("localhost","root","root","learn","users"); 

只要使用此：

Connect_Show("localhost","root","root","learn","users"); 

Connect_Show is a function, with echo commands in it, its not returning anything.
