Try this:

<?php for ($i = 0; $i < 5; $i++) { ?>
    <div class="row">

        <div class="col-md-3">
            <div class="form-group">
                <label>Name</label>
                <input name="data[item<?php echo $i; ?>][<?php echo 'fname' . $i ?>]" class="form-control" type="text"/>
            </div>
        </div>
        <div class="col-md-3">
            <div class="form-group">
                <label>Surname</label>
                <input name="data[item<?php echo $i; ?>][<?php echo 'sname' . $i ?>]" class="form-control" type="text"/>
            </div>
        </div>
        <div class="col-md-3">
            <div class="form-group">
                <label>Date of Birth</label>
                <input name="data[item<?php echo $i; ?>][<?php echo 'dob' . $i ?>]" class="date-pick-years form-control" type="text"/>
            </div>
        </div>
    </div>

<?php } ?>

You will get:

$_POST['data'] = array (
    'item0' =>
        array (
            'fname0' => '',
            'sname0' => '',
            'dob0' => '',
        ),
    'item1' =>
        array (
            'fname1' => '',
            'sname1' => '',
            'dob1' => '',
        ),
    'item2' =>
        array (
            'fname2' => '',
            'sname2' => '',
            'dob2' => '',
        ),
    'item3' =>
        array (
            'fname3' => '',
            'sname3' => '',
            'dob3' => '',
        ),
    'item4' =>
        array (
            'fname4' => '',
            'sname4' => '',
            'dob4' => '',
        ),
);

If you want to use them in variables you can extract it:

$data = $this->input->post('data');
if(is_array($data)) {
    extract($data);
    if(isset($item1)) {
        var_export($item1);
// it will contains:
//        array (
//            'fname1' => '',
//            'sname1' => '',
//            'dob1' => '',
//        );
    }
}

If you want to get an array of values that belong semantically to the same name value, use [] in your html:

    <div class="col-md-3">
        <div class="form-group">
            <label>Name</label>
            <input name="fname[<?=$i?>]" class="form-control" type="text" />
        </div>
    </div>

Then use the usual $data = $this->input->post() in your controller to read out the data. The data should be in this format:

$post[
       fname [
           0 => 'name1',
           1 => 'name2',
           ...
       ],
       sname [
           0 => 'sname1',
           1 => 'sname2',
           ...
       ],
       ...
   ]
]

Update: Format this into the format you want

$resultArray = array();
for($i = 0; $i < <formlength>; $i++) {
    $resultArray[$i]['fname'] = $post['fname'][$i];
    $resultArray[$i]['sname'] = $post['sname'][$i];
    ...
}

<?php for ($i=0;$i<5;$i++) {?>
                <div class="row">

                <div class="col-md-3">
                    <div class="form-group">
                        <label>Name</label>
                        <input name="name[<?=$i?>][fname]" class="form-control" type="text" />
                    </div>
                </div>
                <div class="col-md-3">
                    <div class="form-group">
                        <label>Surname</label>
                        <input  name="name[<?=$i?>][sname]" class="form-control" type="text" />
                    </div>
                </div>
                <div class="col-md-3">
                    <div class="form-group">

            <input type="submit" />
