>伙计们,我有多维数组,我从var_dump
$menu_order
中得到它,具有以下数组:
array(5) {
[0]=>
array(1) {
[0]=>
array(1) {
["variant_name"]=>
string(5) "Spicy"
}
}
[1]=>
array(2) {
[0]=>
array(1) {
["variant_name"]=>
string(5) "Spicy"
}
[1]=>
array(1) {
["variant_name"]=>
string(5) "small"
}
}
[2]=>
array(2) {
[0]=>
array(1) {
["variant_name"]=>
string(5) "Salty"
}
[1]=>
array(1) {
["variant_name"]=>
string(6) "medium"
}
}
[3]=>
array(2) {
[0]=>
array(1) {
["variant_name"]=>
string(12) "Mix of Herbs"
}
[1]=>
array(1) {
["variant_name"]=>
string(5) "large"
}
}
[4]=>
array(0) {
}
}
从该数组中,我需要使用以下代码获取variant_name
变得variant_menu_id
:
foreach ($menu_order as $item) {
if (isset($item[0]["variant_name"])) {
foreach($item as $value) {
$variant_id[] = $this->Main_home_m->m_get_choice_id($value["variant_name"]);
}
} else {
$variant_id[] = array();
}
}
m_get_choice_id
的模型有以下代码:
Function m_get_choice_id($variant_name){
$this->db->select("variant_menu_id");
$this->db->from("uhd_variant_menu");
$this->db->where("variant_name",$variant_name);
$query = $this->db->get();
return $query->row_array();
}
variant_id
将返回到这个多维数组:
array(8) {
[0]=>
array(1) {
["variant_menu_id"]=>
string(1) "3"
}
[1]=>
array(1) {
["variant_menu_id"]=>
string(1) "3"
}
[2]=>
array(1) {
["variant_menu_id"]=>
string(1) "6"
}
[3]=>
array(1) {
["variant_menu_id"]=>
string(1) "4"
}
[4]=>
array(1) {
["variant_menu_id"]=>
string(1) "7"
}
[5]=>
array(1) {
["variant_menu_id"]=>
string(1) "5"
}
[6]=>
array(1) {
["variant_menu_id"]=>
string(1) "8"
}
[7]=>
array(0) {
}
}
但我希望结果variant_id
这个多维数组:
array(5) {
[0]=>
array(1) {
[0]=>
string(1) "3"
}
[1]=>
array(2) {
[0]=>
string(1) "3"
[1]=>
string(1) "6"
}
[2]=>
array(2) {
[0]=>
string(1) "4"
[1]=>
string(1) "7"
}
[3]=>
array(2) {
[0]=>
string(1) "5"
[1]=>
string(1) "8"
}
[4]=>
array(0) {
}
}
伙计们你能帮我如何获得多维数组吗?
谢谢 (:
或者,您可以创建一个临时容器,其中包含一个数组的 id。将它们全部作为一个数组获取后,将整个批次推送到父容器中:
$result = array();
foreach ($menu_order as $item) {
$temp = array(); // initialize temporary storage
if (isset($item[0]["variant_name"])) {
foreach($item as $value) {
$variant = $this->Main_home_m->m_get_choice_id($value["variant_name"]);
$temp[] = $variant['variant_menu_id']; // push single id into temporary storage
}
}
$result[] = $temp; // push ending batch
}
