How to loop through an array inside of array in php?

I'm trying to loop through an array inside of an array, so that I can display either phone numbers or extension number. For example: If a user has both (phone number and extension number) then I should ONLY display phone number, but sometimes a user has only a extension number then I should display the extension number.

Here's my array of customers:

(
  [status] => Array
    (
        [resultCode] => 00000
        [context] => COMPLETED
    )

[searchUserResults] => Array
    (
        [searchUserResult] => Array
            (
                [0] => Array
                    (
                        [userId] => AllieCraig
                        [phoneNumber] => 13039453156

    )

)

And here's my code:

  <table style="padding: 40px;margin-left: -10px;margin-top:-38px;display: inline-block;">
            <div style="margin-top:16px;margin-left:10px;">
                <input type="checkbox" id="checkAll"/>
            </div>
            <div style="padding:20px;">
                @foreach($resultArray as $key => $value)

                    @foreach($value as $key2 => $value2)
                        @if(is_array($value2))
                            @foreach($value2 as $key3 => $value3)
                                <?php
                                   // echo var_dump($value3["firstName"]);

                                if (in_array($value3['phoneNumber'], $value3)) {
                                    if (strlen($value3['phoneNumber']) === 11) {
                                        $value3['phoneNumber'] = ltrim($value3['phoneNumber'], 1);
                                    }
                                }
                                else{
                                    $value3['phoneNumber'] = $value3['extension'];
                                }



                                ?>

                                <tr>
                                    <td>
                                        <input class="input_checkbox" type="checkbox"
                                               id="customer-name-checkbox" name=" "
                                               value="yes"><span style="padding-left:40px;"></span>
                                    </td>
                                    <td>  </td>
                                    <td>}</td>
                                    <td><input style="margin-left:60px;float: right;" type="email" class="styled-text  rounded" name="" id="customer-name-inputField" placeholder="" value=""/><br/><br/>
                                    </td>
                                </tr>
                            @endforeach
                        @endif
                    @endforeach
                @endforeach
            </div>
        </table>

Can someone tell me what I'm doing wrong please? Thank you so much in advance!!
