Laravel Foreach Looping

I need to display the previous value of the iterated array, here is code

<tr>
    <th></th>
    <th>Customer ID</th>
    <th>Customer Name</th>
    <th>Delivery Address</th>
    <th>Contact No.</th>
    <th>Zip Code</th>
    <th>Payment Terms</th>
    <th>Credit Limit</th>
</tr>
<?php $previousValue = null; ?>
@foreach($customer_count as $key => $value)
    <tr>
        <td>{{$previousValue=$value->customer_name }}</td>
        <td>{{ $value->id }}</td>
        <td>{{ $value->customer_name }}</td>
        <td>{{ $value->delivery_address }}</td>
        <td>{{ $value->contact_number }}</td>
        <td>{{ $value->area_id }}</td>
        <td>{{ $value->payment_term_id }}</td>
        <td>{{ $value->credit_limit }}</td>
    </tr>
@endforeach

I need to display the previous name of Customer in the iteration? Any idea on how to do this?

At very first set the previous value as blank and then at the bottom set value in $previousValue 

<?php $previousValue = '';?>
@foreach($customer_count as $key => $value)
    <tr>
        <td>{{ $previousValue }}</td>
        <td>{{ $value->id }}</td>
        <td>{{ $value->customer_name }}</td>
        <td>{{ $value->delivery_address }}</td>
        <td>{{ $value->contact_number }}</td>
        <td>{{ $value->area_id }}</td>
        <td>{{ $value->payment_term_id }}</td>
        <td>{{ $value->credit_limit }}</td>
    </tr>
    <?php $previousValue = $value->customer_name; ?>
@endforeach

please try this

<td>{{ (!$loop->first) ? $customer_count[$key - 1]->customer_name : '' }}</td>

$customer_count[$key - 1]

Of course you'll need to check if that exists or use the null-coalesce operator or something, so:

@php

$previous = $customer_count[$key - 1] ?? false;

@endphp

Then use:

@if( $previous ) 
... some stuff ...
@endif

wherever you need to inject.
