I have a problem to sum the values ​​using foreach. enter image description here

I want to add the value of 12000 to 11000 but the result is only 11000, which is the last data.

$no = 1;
foreach ($record->result_array() as $calc) {
    $sum = 0;
    $sum += $calc['harga_jual'] - $calc['diskon'];
    $no++;
}

The initialization of variable $sum ...is meant to be outside the foreach loop ...

That is $sum = 0 is meant to be outside the foreach loop ...

Note:- The declaration & initialization of $sum = 0; is outside the foreach loop.

<?php 
    
    $sum = 0;
    foreach ($record->result_array() as $calc) 
    {
       $sum += $calc['harga_jual'] - $calc['diskon'];
    }
    echo $sum;
    ?>
