// Instead of:
$data_final2[] = $line123['answer_name']; ❌

// Use this:
$data_final2[$line123['answer_name']] = $line123['answer_name']; ✅

// Instead of:
 $finaldata1[] = array("fullname"=>$fullname,"email"=>$email,"type"=>$type,"name"=>$name,"data_final2"=>$data_final2 ); ❌

// Use this:
 $finaldata1[] = array_merge(array("fullname"=>$fullname,"email"=>$email,"type"=>$type,"name"=>$name), $data_final2); ✅

You can use something like this

$finaldata = [
    'fullname' => 'John',
    'email' => '[email protected]',
    'type' => 'Admin',
    'name' => '',
    'data_final1' => [
        'IOS 8','Expert','Sachin',
    ],
];

$data_final2 = [];
foreach($finaldata['data_final1'] as $value){
    $data_final2[$value] = $value;
}
unset($finaldata['data_final1']);
$finaldata = array_merge($finaldata , $data_final2);

print_r($finaldata);

The output from this code is

Array
(
    [fullname] => John
    [email] => [email protected]
    [type] => Admin
    [name] => 
    [IOS 8] => IOS 8
    [Expert] => Expert
    [Sachin] => Sachin
)

Note: if you're using old php version use array() instead of []

It looks like fullname, email, type, and name can be created before the loop and can be assigned to $finaldata1.

$finaldata1 = compact('fullname', 'email', 'type', 'name');

Then looping through $data_final1 and add both key and value directly to $finaldata1

foreach ($data_final1 as $line123) {
    $finaldata1[$line123['answer_name']] = $line123['answer_name'];
}

So the final code in the loop should look like this.

for ($la = 0; $la < count($finaldata); $la++) {
    ...
    ...
    $finaldata1 = compact('fullname', 'email', 'type', 'name');

    foreach ($data_final1 as $line123) {
        $finaldata1[$line123['answer_name']] = $line123['answer_name'];
    }
}

This solution uses array_combine() and array_merge().

$data_final1 = $finaldata['data_final1'];
unset($finaldata['data_final1']);
$finaldata = array_merge($finaldata, array_combine($data_final1,$data_final1));
