Recursive Deduction of array - php

Question

Hi I have this array values
# amount deduction
[0] 50 10
[1] 160 20
[2] 300 20
I want to have a recursive deduction of these arrays until data is zero, and then if the first amount of the array is zero(0) the deduction will add to the next data, until all amount will be zero (0). Sample Calculation below
[0] [1] [2]
50 - 10 160 - 20 300 - 20
40 - 10 140 - 20 280 - 20
30 - 10 120 - 20 260 - 20
20 - 10 100 - 20 240 - 20
10 - 10 80 - 20 220 - 20
0 60 - 30 200 - 20
30 - 30 180 - 20
0 160 - 50
110 - 50
60 - 50
10 - 50
0
I don't know how to do it but this is my code so far.
foreach($data as $det)
{
$_monthly_payment = $det->deduction;
$_beginning_balance = $det->amount;
$i = 0;
do{
$_new_balance = (($i + 1) == 1) ? $_beginning_balance : $_ending_balance;
$_toward_principal = $_monthly_payment;
$_ending_balance = $_new_balance - $_toward_principal;
<tr>
<td><?php echo number_format($_monthly_payment,2); ?></td>
<td>$<?php echo number_format($_new_balance,2); ?> </td>
<td>$<?php echo number_format($_toward_principal,2); ?> </td>
<td>$<?php echo number_format($_ending_balance,2); ?> </td>
</tr>
}
while( $i <= $_ending_balance );
}
Please don't judge me guys, I just need this so badly. Thank you guys.

Result of my var_dump

}
}

Answer 1

this is the answer big help of #CBroe. This will continue the deduction if the first data of the array is zero(0).
<?php
$data = [
['amount' => 50, 'deduction' => 10],
['amount' => 160, 'deduction' => 20],
['amount' => 300, 'deduction' => 20],
];
$continue = true;
echo '<table>';
while($continue) {
$continue = max(array_column($data, 'amount')) > 0;
echo '<tr>';
for($i=0; $i<count($data); ++$i) {
echo '<td>';
echo !isset($data[$i]['done']) ? max($data[$i]['amount'], 0) : '';
if($data[$i]['amount'] <= 0 && !isset($data[$i]['done'])) {
$data[$i]['done'] = true;
if(isset($data[$i+1])) {
$data[$i+1]['deduction'] += $data[$i]['deduction'];
}
}
echo !isset($data[$i]['done']) ? ' - '.$data[$i]['deduction'] : '';
echo '</td>';
$data[$i]['amount'] -= $data[$i]['deduction'];
}
echo '</tr>';
}
echo '</table>';
