    [0] => Array
        (
            [s_id] => 4
            [si_id] => sec_1
            [d_id] => dep_4
            [s_name] => sec1
            [s_location] => LA
            [s_visibility] => yes
            [s_created_date] => 1273639343
            [s_last_updated_date] => 1273639343
            [s_created_by] => someone
            [s_last_updated_by] => everyone
        )

)

now i want to extract array[0] into an array… means i want this

Array
(
            [s_id] => 4
            [si_id] => sec_1
            [d_id] => dep_4
            [s_name] => sec1
            [s_location] => LA
            [s_visibility] => yes
            [s_created_date] => 1273639343
            [s_last_updated_date] => 1273639343
            [s_created_by] => someone
            [s_last_updated_by] => everyone

)

how do i get above results?

Answer 1

You can do:

$newArray = $oldArray[0];

This will create a new array with the same key-value pairs.

If you do not want to create a new array and want the new array to refer to the existing array in the $oldArray you can do:

$newArray = &$oldArray[0];

Any changes made to $newArray will also change $oldArray in this case.
