PHP not showing all data in array from loop - php

Question

Outputting data to an array
public function GetProfitByMonth($d1, $d2){
$sql=odbc_exec($this->connections, "select con.ID, con.ShortName as NameAK,
ROUND(ISNULL(SUM(tik.TotalSub)-SUM(tik.TotalAG), 0), 2) as Profit,
MONTH(tik.DEALDATE) as month_num
from Counteragent as con
left join Tickets as tik on tik.AgentID=con.ID
where con.ValueType in (2,3) and con.Active='1' and (DEALDATE between '".$d1."' and '".$d2."')
group by con.ID, con.ShortName, MONTH(tik.DEALDATE)
order by con.ShortName, MONTH(tik.DEALDATE) ;");
$tblResult=array();
while ($row = odbc_fetch_array($sql)) {
$tblResult[]=$row;
}
odbc_free_result($sql);
Array
(
[0] => Array
(
[Profit] => 11218.30
[month_num] => 8
)
[1] => Array
(
[Profit] => 1152.15
[month_num] => 8
)
....
[4] => Array
(
[Profit] => 119837.81
[month_num] => 8
)
)
I need to display only month_num => Profi from the array
did this way
$tblResult = array();
while ($row = odbc_fetch_array($sql)) {
$tblResult[$row['mon_num']] = $row['Profit'];
}
odbc_free_result($sql);
return $tblResult;
but as a result in the array shows only the last value:
Array
(
[8] => 119837.81
)
How to make an array show all the data?

Answer 1

This is because month_num = 8 for all entries in your original array.
Your while loops first two iterations effectively evaluate to:
$tblResult[8] = 11218.30
$tblResult[8] = 1152.15
To get the result in the form you want, you need month_num to be unique.
