How to set manual key value in array instead of index in multi-dimensional array in PHP?

Question

I am using PHP 7.0 for my development. I got

Array
(
    [0] => Array
        (
            [lngCngSecUserId] => 0
            [sdtHolidayDate] => 1
        )

)

as output by following code:

<?php
    $tblActualHoliday = array();
    $arrColFields= array();
    $arrColFields["lngCngSecUserId"] = 0;
    $arrColFields["sdtHolidayDate"] = 1;
    array_push($tblActualHoliday,$arrColFields);
    print_r($tblActualHoliday);
?>

but I want output as

Array
(
    [ColHeader] => Array
        (
            [lngCngSecUserId] => 0
            [sdtHolidayDate] => 1
        )

)

How can I get it? I want ColHeader instead of 0 as index key.

You can set "ColHeader" as a key for entry in $tblActualHoliday the same way as "lngCngSecUserId" for $arrColFields.

    $arrColFields= array();
    $arrColFields["lngCngSecUserId"] = 0;
    $arrColFields["sdtHolidayDate"] = 1;

    $tblActualHoliday["ColHeader"] = $arrColFields;

?>
