Question

我正在研究从mySQL数据库中提取数据的方法，并将文本显示为数组但是我有这样的方式，因此只有一个数据字符串可用，每个实例都用逗号示例分隔。 1,2,3,4有没有办法让它在每个逗号之后断开或开始一个新行，而不是像这样的集合混乱：

1 package KRAFT Deluxe Macaroni & Cheese Dinner Sharp Cheddar Cheese Sauce, 1 lb Ground Beef, 1 Jar Spaghetti Sauce, 1/2 Cup KRAFT Shredded Mozzarella Cheese

代码：

<?php

require_once '../scripts/app_config.php';
require_once '../../scripts/authorize.php';
require_once '../scripts/database_connection.php';

// Get the user ID of the user to show
$User_id = $_REQUEST['User_id'];

// Gets User Id
$select_query = "SELECT * FROM users WHERE User_id = " . $User_id;

// Run the query to get User Name
$result1 = mysql_query($select_query);
if ($result1) {
  $row = mysql_fetch_array($result1);
  $first_name     = $row['First_name'];
  $last_name      = $row['Last_name'];
  $email          = $row['Email'];
  $User_id          = $row['User_id'];

} else {
  handle_error("There was a problem finding your " .
               "information in our system.",
               "Error locating user with ID {$User_id}");

}

$Recipe_Id = $_REQUEST['Id'];

$result = mysql_query( "SELECT * FROM recipes WHERE Id = " . $Recipe_Id ) 
        or die(mysql_error());  

while($row = mysql_fetch_array($result))
{
    $Id = $row['Id'];
      $Name =      $row['Name'];
    $Ingredients = $row['Ingredients'];
    $Category1 =   $row['Category1'];
    $Category2 =   $row['Category2'];
    $Directions =  $row['Directions'];
    $Creator =     $row['User_Name'];

Answer 1

如果我说得对，你只需要这样的东西：

echo "<p>" . str_replace(', ',', <br />',$row['Ingredients']) . "</p>";

根据标点符号将项目放入数组中
