将搜索结果导出到.CSV，PHP-MySQL

我还是PHP MySQL的初学者。我正在寻找将

搜索数据导出到
的最有效/最简单的方法

场景：

我想有一个导出按钮，搜索结果可以导出到
.CSV
像这样

也许这个过程是这样的：

搜索您想要的任何数据>（单击搜索按钮）

如果未找到结果>提示错误>模具

如果找到任何记录>显示>（单击导出按钮）>导出到.CSV



这是我的搜索表单代码：

  <?php
  session_start();
  include_once "dbconnect.php";
  date_default_timezone_set('Hongkong');


  //LOG IN VALIDATION
  if(!isset($_SESSION['user']))
  {
  header("Location: index.php");
  }
  $res=mysql_query("SELECT * FROM accounts WHERE user_id=".$_SESSION['user']);
  $userRow=mysql_fetch_array($res);   

  ?>

  //HTML SEARCH FORM IS HERE
    //SEARCH BUTTON <br/><h5 style="float:right;"><button type="submit" class="btn btn-theme02" name="search" ><i class="fa fa-check">Search Customers</i></button></h5>

  //BUTTON FOR IMPORTING THE SEARCHED DATA INTO CSV
  //DONT HAVE FUNCTION YET DON'T KNOW HOW TO EXPORT THE DATA 
  <button type="submit" name="EXPORT">EXPORT TO CSV</button>


 <?php
 $number = 1;//NOT IMPORTANT, JUST USE TO NUMBERING THE ITEMS SEARCHED

 //TABLE 
 echo "<table class=\"table table-hover\" id=\"table1\" >";
          //TABLE ROW NAMES - SQL TABLE 
            echo " <hr><thead><tr>";
          echo "<th></th>";
            echo "<th>Globe Number</th>";
          echo "<th>Full Name</th>";
          echo "<th>State</th>";
          echo "<th>Country</th>";
          echo "<th>Virtual Number</th>";
          echo "<th>Date of Subscription</th>";
          echo "<th>Expiration Date</th>"; 
          echo "<th></th>";
          echo "</tr></thead>";       

          //FUNCTION OF SEARCH BUTTON 
          if (isset($_POST['search'])) {
          $globe = htmlentities(mysql_real_escape_string($_POST['globe']));
          $name = htmlentities(mysql_real_escape_string($_POST['name']));
          $vr = htmlentities(mysql_real_escape_string($_POST['virtual']));
          $ctry= htmlentities(mysql_real_escape_string($_POST['country']));


          if (empty($globe) && empty($name) && empty($vr) && empty($ctry) && empty($dateStarted)  && empty($dateExpired) 
            && empty($time) && empty($transaction) && empty($subs) && empty($status) && empty($remarks) && empty($year) && empty($month)) {
          echo '<script>alert(\'Select atleast 1 filter\')</script>'; 
          exit;        
         }

          //SEARCH CONDITIONS
          if (!empty($globe)) {
            $sql = "SELECT * FROM `subscribers` WHERE `globeNumber` =  '".$globe."' AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC ";

          }if (!empty($name)) {
           $sql = "SELECT * FROM `subscribers` WHERE  `fName` LIKE  '%".$name."%' OR `lName` LIKE  '%".$name."%'  AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC ";

          }if (!empty($vr)){
           $sql = "SELECT * FROM `subscribers` WHERE `virtualNumber` =  '".$vr."' AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC ";

          }if (!empty($ctry)){
           $sql = "SELECT * FROM `subscribers` WHERE `country` = '".$ctry."' AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC  ";


          //COMBINATION CONDITIONS
          // I MINIMIZE THE CONDITION FOR SEARCH HERE            
         } if (!empty($globe) && !empty($name)) {

          $sql = "SELECT * FROM `subscribers` WHERE `globeNumber` =  '".$globe."' AND `fName` = '".$name."' AND `lName` = '".$name."'   
           AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC ";

        } if (!empty($globe) && !empty($vr)) {

          $sql = "SELECT * FROM `subscribers` WHERE `globeNumber` =  '".$globe."' AND `virtualNumber` = '".$vr."'
           AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC ";

        } if (!empty($globe) && !empty($ctry)) {

          $sql = "SELECT * FROM `subscribers` WHERE `globeNumber` =  '".$globe."' AND `country` = '".$ctry."'
           AND `agentCode`='".$agent."' ORDER BY `dateStarted` DESC ";
      }

        //THE QUERY RUN HERE
        if ($result=mysql_query($sql)) {
            $query_num_rows = mysql_num_rows($result);

              //IF NO RECORD FOUND RUN THIS
               if($query_num_rows == 0){ 
                  echo "<script> alert('No Records Found, Please try again!')</script>"; 

        } else {

         while($row=mysql_fetch_array($result)){

          echo "<tbody><tr>";
          echo "<td>".$number."</td>";
          echo "<td>".$row['globeNumber']."</td>";
          echo "<td>".$row['lName'].", ".$row['fName']." ".$row['mName']."</td>";

          ++$number;//NOT IMPORTANT, JUST USE FOR NUMBERING THE ITEMS SEARCHED

          echo "</form></tr>";
          echo "string";
  }}}} ?>


//HTML搜索表单在这里
//搜索按钮
搜索客户
//用于将搜索数据导入CSV的按钮
//没有功能，但不知道如何导出数据
导出到CSV

PS:我仍然在使用MySQL，因为我想先熟悉一下。
下面的步骤将帮助您

创建用于检索搜索结果记录的函数
验证输入并调用此函数，然后以数组/对象的形式返回值
如果结果为空，则返回false
显示获取的记录
如果“单击导出”，则使用一个导出标志提交相同的搜索值
检查您设置的标志并调用相同的函数进行搜索
设置下载CSV文件的标题
使用“|”或“，”等分隔符打印结果
@德鲁：是的，我报告删除了，先生。还宽吗，先生？我的问题是
如何将搜索表单的结果导出到csv？
我要求您至少显示一些您想要的示例输出，并首先转向mysql。不是用这样的输出来改进问题（说您看到的只是PHP代码），而是堆栈上没有其他引用起作用，您知道rest@Drew：我明白了，先生，我很快就会编辑这个。谢谢您能提供一个这个实现的工作示例吗？谢谢
