            [1] =>

            [8] => No miscompares for both scan and logic tests
            [9] =>

            [1] =>
            [2] =>
            [3] =>
            [4] =>
            [5] => Done
            [6] =>
            [7] => Error if explicitshifts greater than scan length
            [8] => No miscompares for both scan and logic tests
            [9] =>
            [10] =>

            [12] =>
        )

    [3] => Array
        (
            [0] => /s/m/p
            [1] =>
            [2] =>
            [3] =>
            [4] =>
            [5] => Done
            [6] =>
            [7] => 2D Elastic + wide 1 Masking with scanformat=parallel
            [8] => No miscompares for both scan and logic tests
            [9] =>
            [10] =>
            [11] =>
            [12] =>
        )

)

I want to set the numeric keys [0]....[12] as the values of $headers array. Means i want to replace [0]....[12] with $header[0]....$headers[12].

Please provide a solution.

Answer 1

Use array_combine :

$dataWithKeys = [];
foreach ($data as $row) {
    $dataWithKeys[] = array_combine($headers, $row);
}

Answer 2

$result = array();
foreach($data as $key => $val){
    $temp = array(); 
    foreach($val as $k => $v){
       $temp[$header[$k]] = $v; 
    }
    $result[] = $temp;
}
