在while和for循环php之外访问结果

Question

我为我的用户设置了开始和结束时间

时间在 db 中以秒为单位，并在页面中的 gmdate() 中转换 看到整数时请记住。

 user1 startTime = 9:00;  finishTime = 10:00;
 user2 startTime = 12:00;  finishTime = 1:00;

 <?php

 if ($results = $db->query("SELECT * FROM times WHERE Id = $user->data()->id")){
    if($results->num_rows){

       $value = 1800;

      while($row = $results->fetch_array()){

         //This will return the startTime, finishTime, and any blocks of time in between them
         for($n_block = $row['timeStart']; $n_block <= $row['timeFinish']; $n_block+=$value){
            echo "$n_block<br>";
        }
     }
   }
 }
 ?>

 The desired results are:
 32400
 34200
 36000
 43200
 45000
 46800

但我需要将结果放入循环外访问的数组中

   // need to get above while and for loop results in this array outside the loops
   $excludes = array();

如果我使用 $start = ""; 请看http://pastie.org/9784700

如果我将 for 循环从 while 循环中取出 请看http://pastie.org/9784732

我怎样才能达到预期的效果？意思是如何在循环之外访问组合循环的结果？

var_dump($row);

array(18) { 
    [0]=> string(1) "5"
    ["appointmentCount"]=> string(1) "5"
    [1]=> string(2) "23"
    ["technicianId"]=> string(2) "23"
    [2]=> string(2) "22"
    ["customerId"]=> string(2) "22"

<?php
if ($appointmentResults = $db->query("SELECT * FROM appointments WHERE technicianId = $userid")){
    if($appointmentResults->num_rows){
        $start = "";
        $finish = "";
        $value = 1800;

        while($row = $appointmentResults->fetch_array()){
            $start .= $row['appointmentStart'] . '<br>';
            $finish .= $row['appointmentFinish'] . '<br>';

            for($n_block = $row['appointmentStart']; $n_block <= $row['appointmentFinish']; $n_block+=$value){
                echo "$n_block</br>"
            }
        }
    }
}

Answer 1

在脚本的开头，if 之前，添加：

    $excludes = array();

在您的循环中，就在echo 之前，添加：

    $excludes[] = $n_block;

当您退出 if 时，$excludes 将是您想要的整数数组。

如果查询没有找到任何记录，$excludes 将是一个空数组。

Answer 2

$excludes = array();
if($appointmentResults = $db->query("SELECT * FROM appointments WHERE technicianId = $userid")) {
    if($appointmentResults->num_rows) {
        $value = 1800;
        while($row = $appointmentResults->fetch_array()) {
            for($n_block = $row['appointmentStart']; $n_block <= $row['appointmentFinish']; $n_block+=$value){
                echo $n_block."</br>";
                $excludes[] = $n_block;
            }
        }
    }
}
sort($excludes);
print_r($excludes);
