PHP使用mysql列的和填充数组

我是一个编程新手。我试图从MySQL表中创建一个数组，稍后我将使用它在PHP/Javascript中创建一个图形

整个想法是，我想制作一个数组，填充代表一年中每个星期的数据。因此，一个包含52个条目的数组（让我们忘记有时发生的第53周）

我的数据库：

我的数据库中有一个表，用于：

+-------------------------+ I production I +-------------------------+ I Shift I (number) I <-ranging from 1 to 3 (different shifts people make) I Line I (number) I <-ranging from 1-8 (different 'conveyor belts') I Products I (number) I <-ranging from 0- a lot! (To be entered in a form) I Week I (number) I <-ranging from 1 to 52 +-------------------------+ 我可以通过添加52个不同的MySQL查询来做到这一点，唯一的区别是week='x'在哪里

到目前为止，我只是在试验interwebz上的代码

任何帮助都将不胜感激！：D

来自荷兰的问候语

只要去掉WHERE子句，你就会得到每周的结果

$result = mysql_query("SELECT week, SUM(products) AS total 
  FROM production GROUP BY week");

结果将作为结果集中的连续行返回，您可以将它们放入数组中：

$sum_by_week = array();
while ($row = mysql_fetch_assoc($result)) {
  $sum_by_week[$row["week"]] = $row["total"];
}

PS：您没有要求这样做，但是您应该知道mysql_*函数正在被弃用。对于新的PHP应用程序，应该开始使用mysqli函数或PDO。只有在维护现有应用程序的情况下，才值得继续使用旧的mysql_*函数。

对于使用mysql而不是另一个扩展，提前表示歉意。；-）

您当前使用的SQL查询是什么？我认为您只需返回相应的结果，然后在PHPI中进行处理。我认为您可能希望GROUP BY在weekAlso之前收集结果。因此，“周数”有一个ISO标准。您可能希望检查您的数字是否一致。我正在使用的当前MySQL查询=
MySQL\u查询（“每周从production WHERE week='1'GROUP BY week中选择周，求和（产品））（每一个新条目一周一次。因此，此查询52次）可能会忽略WHERE子句。您好，Ray Paseur，首先，感谢您的回答。代码似乎没有错误，因为我可以在这里运行它。但我不能回显阵列。。。当错误报告级别被抑制时，空白屏幕通常是PHP解析错误的症状。将这两行添加到脚本顶部：错误报告（E_ALL）；ini设置（“显示错误”，真）；
$sum_by_week = array();
while ($row = mysql_fetch_assoc($result)) {
  $sum_by_week[$row["week"]] = $row["total"];
}
