Sum php array (created from mysql results) depending on mysql values in another mysql column

Question

One table called 18_7_ChartOfAccounts looks like this:

ID | AccountNumber
-------------
1  | 2310
2  | 2380
3  | 2610

Another table called 2_1_journal looks like this:

ID | Amount | DebitAccount
--------------------------
1  | 26.03  | 2310
2  | 200.00 | 2310
3  | 3.63   | 2380
4  | 119.83 | 2380
5  | 33.86  | 2610
6  | 428.25 | 2610

Aim is to get results that looks like this:

DebitAccount 2310 total is: 226.03
DebitAccount 2380 total is: 123.46
DebitAccount 2310 total is: 462.11

226.03 in this example is total of 26.03 + 200.00

At first mysql code

$query = "SELECT j.Amount, j.DebitAccount FROM 18_7_ChartOfAccounts AS c LEFT JOIN 2_1_journal AS j ON (c.AccountNumber = j.DebitAccount)";
$sql = $db->prepare($query);
$sql->execute();
$data = $sql->fetchAll(PDO::FETCH_ASSOC);

With print_r($data); get long list of arrays like

[31] => Array
    (
        [Amount] => 26.03
        [DebitAccount] => 2310

[32] => Array
    (
        [Amount] => 200.00
        [DebitAccount] => 2310

If in mysql query use SUM(j.Amount) then get only one total amount (suppose total amount of Column Amount).

With

foreach($data as $result){
if(strlen($result['Amount']) > 0 ) {
echo "Amount ". $result['Amount']. "Account name ". $result['DebitAccount']. "<br>";
print_r (array_sum($result));
}
}

Get something like this

Amount 123.97Account name 2310
2433.97Amount 26.03Account name 2310
2336.03Amount 200.00Account name 2310

Any ideas how to get necessary results (marked bold)?

Update

Changed $query to

$query = "SELECT SUM(j.Amount), j.DebitAccount FROM 18_7_ChartOfAccounts AS c LEFT JOIN 2_1_journal AS j ON (c.AccountNumber = j.DebitAccount) group by j.DebitAccount";

with print_r($data); get array like this

Array
(
[0] => Array
    (
        [SUM(j.Amount)] => 
        [DebitAccount] => 
    )

[1] => Array
    (
        [SUM(j.Amount)] => 110900.16
        [DebitAccount] => 2310
    )

[2] => Array
    (
        [SUM(j.Amount)] => 3660.86
        [DebitAccount] => 2380
    )

With array seems all works. Now with foreach changed to echo "Amount ". $result['SUM(j.Amount)']. " Account name ". $result['DebitAccount']. "<br>";

Get

Amount 110900.16 Account name 2310
Amount 3660.86 Account name 2380
Amount 85247.40 Account name 2610

Seems also ok. Thanks

You are going about it wrong. You can get the sum through MySql statement itself.

Use the aggrgate function sum along with group by clause.

Like this,

SELECT DebitAccount,sum(Account) from  2_1_journal group by DebitAccount

Your full code:

$query = " SELECT DebitAccount,sum(Account) as Total from  2_1_journal group by DebitAccount";
$sql = $db->prepare($query);
$sql->execute();
$data = $sql->fetchAll(PDO::FETCH_ASSOC);
foreach($data as $result){
if(strlen($result['Total']) > 0 ) {
echo "DebitAccount ". $result['DebitAccount']. "Total is: ". $result['Total']. "<br>";
print_r (array_sum($result));
}
}

You have to use the GROUP BY in the query

SELECT DebitAccount, SUM(Amount) AS Amount FROM 2_1_journal GROUP BY DebitAccount
