Question

我有一个数据库，其中包含与其他表格链接的客户信息。

我试图创建一个带搜索选项的网页来搜索数据库我的搜索功能正常运行。

我希望能够让输出一次只显示一个结果。我也做到了。

我希望能够使用“下一个”和“上一个”按钮在该查询的不同结果之间循环。
根据我的理解（有点新的编码），搜索完成后，所有数据都被放入一个数组中。此阵列已分配ID 所以搜索＆＃34;史密斯＆＃34;可能有10个结果。阵列中的结果为0-9 我的逻辑是让初始搜索显示结果为0然后当按下Next时函数将RecNum增加1然后重新显示。代码设置为由RecNum搜索，因此Next将显示结果2（数组中的第1行）。

让我的工作就是问题所在。我甚至不确定如何接近这一目的。（我是否提到我是编码的新手。）

现在我正在使用Javascript确保按下按钮上的添加和减少功能正常。我失去了如何将新的RecNum转换为PHP $ RecNum并重新显示数据的方法。
任何有关代码的帮助将不胜感激。我并不喜欢使用JavaScript。我愿意使用_Sessions或AJAX。什么都行得很好。

这是我现在的代码。搜索工作和新搜索按钮工作，但是现在所有Prev和Next按钮都会增加/减少RecNum的数量并将其输出到页面底部。

<?php
require 'Connect.php';
$output = '';
$RecNum = 0;
//$Prev = $RecNum - 1;
//$Next = $RecNum + 1;
//$_Post['Prev'] = $Prev;
//$_Post['Next'] = $Next;


//collect
if(isset($_POST['search'])) {
  $searchq = $_POST['search'];
  // Joins and tables with realationships and allows for searching of the searchable areas
  
  $sql="SELECT aps.*, customers.*, equipment.*, routableip.*
