在php中创建多维数组

Question

I am having trouble trying to figure out how to populate a multi-dimensional array. Let's say I have a table of transactions with various billing dates. First I have an array that retrieves the following 'billed' dates:

Array
(
    [0] => Array
        (
            [BILLED] => 2011-11-18 00:00:00
        )

    [1] => Array
        (
            [BILLED] => 2011-11-22 00:00:00
        )

)

I also have the following query which is currently hard-coded to one of the two 'billed' dates shown above:

$qryOrders = $this->db->query("
       SELECT tblOrders.* 
       FROM tblOrders 
       WHERE tbltc.BILLED = '2011-11-22'"); 
$data['Orders'] = $qryOrders->result_array();

I know that I can very easily determine the count of array items by using count($Orders); but how can I instead pass through each of the 'billed' dates of 2011-11-18 and 2011-11-22 to that I can determine the overall count, for both of the specified dates?

I hope I've explained it clearly enough. I am thinking that I probably need some kind of foreach loop and each time through the loop I could pass in the billed date, and keep track of a running total each time through the loop.

Any ideas would be greatly appreciated. Thanks,

Answer 1

// this is getting all results for a record
$sql = 
<<<sql
SELECT tblOrders.* 
FROM tblOrders 
WHERE tbltc.BILLED between '{$arr[0]}' and '{$arr[1]}'
sql;

// this is to get total count of matched record
// $sql = 'select count(*) from ..';

if you are using CI, you can easily using bind

example:-

$sql = 'SELECT tblOrders.* FROM tblOrders WHERE tbltc.BILLED between ? AND ?';
$this->db->query($sql, array($arr[0], $arr[1]));
