我有如下的数组
data = [
{
"Payment_type":1,
"amount":10000
},
{
"Payment_type":1,
"amount":40000
},
{
"Payment_type":2,
"amount":10000
},
{
"Payment_type":2,
"amount":20000
}
]
现在我需要检查Payment_type = 1是否获得所有金额的Payment_type 1，否则获得其他付款类型的所有金额
我需要输出
Payment type 1
---10000
---40000
Payment type 2
---10000
---20000
我尝试使用以下代码
foreach($data as $d)
{
if($d->Payment_type == 1)
{
echo $d->amount;
}
else
{
echo $d->amount;
}
}
我如何获得这些价值？

在找出数据是类型1还是2后，不是直接回显数量，而是填满2个数组（类型1和类型2）。然后，稍后，迭代这些数组。这样，数据将按类型排序。我的示例将与您的问题完全相同。
$dataOfType1 = array();
$dataOfType2 = array();
foreach($data as $d)
{
if($d->Payment_type == 1)
{
$dataOfType1[] = $d;
}
else
{
$dataOfType2[] = $d;
}
}
// iterate over first array (type 1)
echo "Payment type 1 <br>";
foreach($dataOfType1 as $d){
echo "---".$d->amount . "<br>";
}
// iterate over second array (type 2)
echo "Payment type 2 <br>";
foreach($dataOfType2 as $d){
echo "---".$d->amount . "<br>";
}
修改：在循环之外移动付款类型标头

使用我自编写的类GrumpyHelper编写的函数，有一个名为groupArray的函数。
function groupArray($arr, $group, $preserveSubArrays = false, $preserveGroupKey = false) {
$temp = array();
foreach($arr as $key => $subarray) {
$groupBy = $subarray[$group];
if(!$preserveGroupKey) {
unset($arr[$key][$group]);
}
if(!array_key_exists($groupBy, $temp)) {
$temp[$groupBy] = array();
}
if(!$preserveSubArrays && count($arr[$key])==1) {
$temp[$groupBy][] = current($arr[$key]);
} else {
$temp[$groupBy][] = $arr[$key];
}
}
return $temp;
}
您可以将数据插入此功能，如下所示：
print_r(groupArray($data, "Payment_type", false, false));
这会得到结果：
Array
(
[1] => Array
(
[0] => 10000
[1] => 40000
)
[2] => Array
(
[0] => 10000
[1] => 20000
)
)
密钥等于原来的Payment_type。
现在你只需要循环来获得总数。
$totals = [];
foreach($data_from_groupArray as $key => $amounts) {
foreach($amounts as $amount) {
if(empty($totals[$key])) $totals[$key] = 0;
$totals[$key] += $amount;
}
}
这会给你结果：
Array
(
[1] => 50000
[2] => 30000
)
如果密钥等于前Payment_type，则该值等于一起添加的所有金额。
或者，对于您在上面指定的输出，请执行此操作而不是上面的循环：
foreach($data_from_groupArray as $key => $amounts) {
echo "Payment type {$key} <br>";
foreach($amounts as $amount) {
echo " ---{$amount}<br>";
}
}
注意：无论您有多少Payment_type个@model InventoryModule.Models.Masters.Ledger

假设您的数据符合所显示的顺序（即数组按payment_type排序），这将适用于：
<?php
$data = array(array("Payment_type"=>1,"amount"=>10000),
array("Payment_type"=>1,"amount"=>40000),
array("Payment_type"=>2,"amount"=>10000),
array("Payment_type"=>2,"amount"=>20000)
);
#var_dump($data);
$currenttype = 0;
foreach($data as $d)
{
if ($currenttype != $d['Payment_type'])
{
echo " Payment type $d[Payment_type]<br>";
$currenttype=$d['Payment_type'];
}
echo " ---$d[amount]<br>";
}
?>
将为您提供您想要的输出，但在现实生活中使用CSS更好。
输出：
Payment type 1
---10000
---40000
Payment type 2
---10000
---20000

create function，它将$id作为参数并返回过滤后的数据：
function get_by_type($id, $array){
$arr = array();
foreach($array as $a){
if($a['Payment_type'] == $id){
array_push($arr, $a);
}
}
return $arr;
}
