有人可以解释如何从以下数组中获取此结果吗?这是我要找的结果:
Array
(
[Nov 18, 2011] => Array
(
[C] => 2
[I] => 1
)
[Nov 22, 2011] => Array
(
[C] => 2
)
)
这是包含原始数据的数组:
Array
(
[0] => Array
(
[0] => Array
(
[Nov 18, 2011] => C
)
[1] => Array
(
[Nov 18, 2011] => C
)
[2] => Array
(
[Nov 18, 2011] => I
)
)
[1] => Array
(
[0] => Array
(
[Nov 22, 2011] => C
)
[1] => Array
(
[Nov 22, 2011] => C
)
)
)
显示的第一个数组表示内部数组的每个元素的项数,这是我试图从下一个数组中总结的。感谢。
以下是生成上述算法的查询:
$qrybilled = $this->db->query("SELECT tbltc.BILLED FROM tbltc WHERE tbltc.PN = $pn AND tbltc.Y = $taxyear AND tbltc.SCENARIO = $scenario GROUP BY BILLED");
$x = 0; $arr_billed = array();
foreach ($qrybilled->result() as $row) {
$qry3 = $this->db->query("SELECT tbltc.* FROM tbltc WHERE tbltc.PN = $pn AND tbltc.Y = $taxyear AND tbltc.SCENARIO = $scenario AND tbltc.BILLED = '".$row->BILLED."' GROUP BY TC ORDER BY CAT ASC, TC ASC");
$tmp3 = array();
foreach ($qry3->result() as $row) {
$tmp3[] = array( date("M d, Y",strtotime($row->BILLED)) => $row->CAT);
}
$arr_billed3[] = $tmp3;
}
$data['billed3'] = $arr_billed3;
答案 0 :(得分:4)
$arr[0][] = array('Nov 18, 2011'=>'C');
$arr[0][] = array('Nov 18, 2011'=>'C');
$arr[0][] = array('Nov 18, 2011'=>'I');
$arr[1][] = array('Nov 22, 2011'=>'C');
$arr[1][] = array('Nov 22, 2011'=>'C');
$result = array();
foreach($arr as $key=>$value){
foreach($value as $k=>$v){
foreach($v as $_k=>$_v){
if(isset($result[$_k][$_v])){
$result[$_k][$_v]++;
}
else {
$result[$_k][$_v] =1;
}
}
}
}
数组结果:
print_r($result);
Array
(
[Nov 18, 2011] => Array
(
[C] => 2
[I] => 1
)
[Nov 22, 2011] => Array
(
[C] => 2
)
)

$food = array('0' => array('orange', 'banana', 'apple','jack'),
'1' => array('carrot', 'collard', 'pea'));
echo count($food); // output 2
echo count($food[0]) // output 4
echo count($food[1]) // output 3
