用 mysql 填充二维数组 fetch 结果为 php

Question

我刚刚有了一个用于创建图表的框架，这就是它正常工作的方式。

$p = new chartphp();
$p->data = array(array(
array("A",2),
array("B",3),
array("C",23),
array("D",10)   
));
$p->chart_type = "bar";
// Common Options
$p->xlabel = "My X Axis";
$p->ylabel = "My Y Axis";
$out = $p->render('c1');

这种方式工作得很好，现在我需要从 sql 查询中获取结果并填充数组。

$query ="SELECT t.date AS dates,COUNT(t.id) AS trans FROM Gab AS g, Transaction AS t WHERE t.date BETWEEN '2015-07-30' AND '201-07-10' AND g.TID = '1401009' ORDER BY DATES";
$ask = mysql_query($query) or die("Error");
//Now I try to load the results into the array to be integrated into the API.

$p = new chartphp();
$p->data = array(array(
while($recon = mysql_fetch_array($ask)
{
array($recon['dates'],recon['trans']),
}
));
$p->chart_type = "bar";
// Common Options
$p->xlabel = "My X Axis";
$p->ylabel = "My Y Axis";
$out = $p->render('c1');

我试过了，但它不起作用，数组似乎没有加载！

我实际上不确定像你这样嵌套 while 会做什么，我目前无法进行实验，但像这样的事情应该会让你朝着正确的方向前进：

$p->data = array(array());
while($recon = mysql_fetch_array($ask))
{
  $p->data[0][] = array($recon['dates'], $recon['trans']);
}

正在初始化数组，然后在循环中追加元素。
