php - 将现有的 php 搜索重构为 OOP

Question

祝大家新年快乐!

我有这个现有的 php 代码，是我刚开始时做的，我想知道是否有办法使它成为 OOP，或者我是否应该找到另一种重新创建它的方法。欢迎各种意见。

<?php
require("local_php.inc");
DatabaseConnect();

//Variables to post to results.php

$keyword=$_POST['keyword'];
$location=$_POST['location'];
$type=$_POST['type'];

//Query

$q1 = "SELECT ssearch.id, ssearch.Company, ssearch.Address, ssearch_state.state_location, ssearch.City, ssearch.Zip, ssearch.Phone, ssearch.Description, ssearch.Email, 
ssearch_event.Event_name FROM 

(ssearch LEFT OUTER JOIN ssearch_state ON ssearch.State = ssearch_state.id) 

LEFT OUTER JOIN  ssearch_event ON ssearch.Event_id = ssearch_event.id 

WHERE ssearch.Company LIKE '%$keyword%'";

if($location != "all")
{
 $q1 .= "AND ssearch_state.state_location ='$location' "; 
}
if($type != "all")
{
 $q1 .= "AND ssearch_event.Event_name ='$type' "; 
}
$q1 .= "ORDER BY ssearch.Company DESC LIMIT 0, 3;";
$result = mysql_query($q1);
$q1_total_rows = mysql_num_rows($result);

?>
<div id="content"> 
 <?php if($q1_total_rows >= 1) { ?>
 <?php while ($record = mysql_fetch_assoc($result)) { ?>
 <div id="table">
  <table width="379" height="64" border="0" align="left" bordercolor="#FFFF00" bgcolor="#FEFFD5">

我希望您首先确保其安全。读取$_POST输入变量时添加mysql_real_escape_string。就目前而言，您的代码完全依赖 magic_quotes 来工作。

作为第二步，您可以使该代码程序化。设计一个 location_query() 函数或其他东西。我认为没有直接的结构可以有利于跳转到“使其成为 OOP”。
