Sum values in foreach loop in [php] - php

Question

I want to sum tot_Price and unit_Price respectively so that I can analyze the average of these two attributes.
<tr>
<td>{{ $X_land->house_Type }}</td>
<td class="address">{{ $X_land->the_Location }}</td>
<td>{{ $X_land->tot_Price }}</td>
<td>{{ $X_land->tran_Area }}</td>
<td>{{ $X_land->unit_Price }}</td>
<td><button id="opener<?php echo $opencount?>">詳細資訊</button></td>
</tr>
How should I do this?
Thanks.

Answer 1

You could add sum variable for both tot_Price and unit_Price and add in foreach loop
<?php $sum_tot_Price = 0 ?>
<?php $sum_unit_Price = 0 ?>
#foreach ($yourData as X_land)
<tr>
<td>{{ $X_land->house_Type }}</td>
<td class="address">{{ $X_land->the_Location }}</td>
<td>{{ $X_land->tot_Price }}</td>
<td>{{ $X_land->tran_Area }}</td>
<td>{{ $X_land->unit_Price }}</td>
<td><button id="opener<?php echo $opencount?>">詳細資訊</button></td>
</tr>
<?php $sum_tot_Price += $X_land->tot_Price ?>
<?php $sum_unit_Price += $X_land->unit_Price ?>
#endforeach
<tr>
<td>Sum tot_Price {{ $sum_tot_Price}}</td>
<td>Sum unit_Price {{ $sum_unit_Price}}</td>
</tr>

Answer 2

Assume:
#foreach($lands as $X_land)
<tr>
<td>{{ $X_land->house_Type }}</td>
<td class="address">{{ $X_land->the_Location }}</td>
<td>{{ $X_land->tot_Price }}</td>
<td>{{ $X_land->tran_Area }}</td>
<td>{{ $X_land->unit_Price }}</td>
<td><button id="opener<?php echo $opencount?>">詳細資訊</button></td>
</tr>
#endforeach
You can get total like this:
{{$lands->sum('tot_Price')}}
{{$lands->sum('unit_Price')}}
Or you can get average:
{{$lands->avg('tot_Price')}}
{{$lands->avg('unit_Price')}}

Answer 3

To be very simple,
You need to focus on the #foreach loop first,
e.g #foreach($people as $person)
and there is the salary which you can access in foreach,
Through $person->salary
If you want to calculate the sum of salaries then use a simple sum like this,
$people->sum('salary'), Remember not use $person
In your case
{{$lands->sum('tot_Price')}}
{{$lands->sum('unit_Price')}}
