Sorry, cant find what i need. I have xls/xlsx. Then i get smth like this:

    array
    0 => string 'NameFirstColumn'

  1 => 
    array
    0 => string 'qqq'
    1 => float 30

First row is a header with names of values. How to make PHPExcel convert to array looks like:

    array
    NameFirstColumn => string 'qqq'
    NameSecondColumn => float 30

Assuming that you already have this array in $array

$headings = array_shift($array);
array_walk(
    $array,
    function (&$row) use ($headings) {
        $row = array_combine($headings, $row);
    }
);
