我正在嵌套foreach，
foreach ($student_due_fee as $key => $fee) {
foreach ($fee->fees as $fee_key => $fee_value) {
?>
<tr>
<td> <?php echo $fee_value->name; ?></td>
<td> <?php echo $fee_value->fee_groups_id; ?></td>
<td> <?php echo $fee_value->parent_fee_groups_id; ?></td>
<td> <?php echo $fee_value->total_amount ?> </td>
<td> <?php echo $fee_value->group_fee_type ?> </td>
<td> <?php echo $fee_value->group_fee_amount ?> </td>
</tr>
<?php
}
}
?>
结果表看起来像，
group_name group_id parent_group_id amount group_type
One 69 0 3300 I SEM TUTION FEES; II SEM TUTION FEES;
Two 70 0 450 CO - SCHOLASTICS; BOOKS;
Three 71 69 -100 CONCESSION
print_r($fee_value)给出以下内容，
stdClass Object ( [id] => 2 [student_session_id] => 278 [fee_session_group_id] => 15 [is_active] => no [created_at] => 2018-04-19 11:36:57 [fee_groups_feetype_id] => 74 [group_fee_type] => I SEM TUTION FEES; II SEM TUTION FEES; SPORTS FEES [group_fee_amount] => 1000.00; 2000.00; 300.00 [amount] => 1000.00 [total_amount] => 3300.00 [due_date] => 2018-04-24 [fee_groups_id] => 69 [parent_fee_groups_id] => 0 [name] => Ist Term - LKG [feetype_id] => 1 [code] => ISEMTUTION [type] => I SEM TUTION FEES [student_fees_deposite_id] => 0 [amount_detail] => 0 )

如果与组ID和父组ID匹配，我需要两个组的总和，我希望的结果是，
group_name group_id parent_group_id amount group_type
One 69 0 3200 I SEM TUTION FEES; II SEM TUTION FEES; CONCESSION
Two 70 0 450 CO - SCHOLASTICS; BOOKS;
如果父组ID（69）与费用组ID（69）匹配，那么它们将组合为单个组，我需要总结两行的数量并将其显示为一个。这里三个金额需要与第一组中的金额相加，因为与父组匹配。
在foreach中，我试过了，如果喜欢，
foreach ($student_due_fee as $key => $fee) {
foreach ($fee->fees as $fee_key => $fee_value) {
if ($fee_value->parent_fee_groups_id == $fee_value->fee_groups_id) {
echo "string";
}
}
}
?>
但它对我没有帮助。任何给我一个解决方案的帮助，就像我提到的表格一样，我会更加明显......
