resetting the keys two sub-arrays within an array

[rick.emmet]

 

Hi Everyone,

I've been looking online for a way to reset the keys of sub arrays. Heres a portion of what I have:

Array
(
    [userfile] => Array
        (
            [name] => Array
                (
                    [5] => IMG_20170325_152954871_HDR.jpg
                )

            [type] => Array
                (
                    [5] => image/jpeg
                )

            [tmp_name] => Array
                (
                    [5] => /Applications/XAMPP/xamppfiles/temp/phpA49huQ
                )

        )

)

 

I've found a couple of examples that are close to what I'm looking for:

$_FILES = array_map('array_values', $_FILES);

	// And also tried

foreach ($_FILES as &$val) {
            $val = array_values($val); 
}

 

But both of them produce this output:

Array
(
    [userfile] => Array
        (
            [0] => Array
                (
                    [5] => IMG_20170325_152954871_HDR.jpg
                )

            [1] => Array
                (
                    [5] => image/jpeg
                )

            [2] => Array
                (
                    [5] => /Applications/XAMPP/xamppfiles/temp/phpA49huQ
                )
         )
    )

 

I want to go one level deeper and reset the sub array keys like so:

Array
(
    [userfile] => Array
        (
            [name] => Array
                (
                    [0] => IMG_20170325_152954871_HDR.jpg
                )

            [type] => Array
                (
                    [0] => image/jpeg
                )

            [tmp_name] => Array
                (
                    [0] => /Applications/XAMPP/xamppfiles/temp/phpA49huQ
                )
         )
    )

 

Everything I've tried has failed. Any ideas? Thanks so much.

Cheers,

Rick

This smells of an XY Problem. What are you really trying to do. And I don't mean, your attempt at it.

And to add to benanamen's question, why do you need the lowest values in yet another array? If there is just one value for name, type, etc why not have the array in this format

Array
(
    [userfile] => Array
    (
        [name] => IMG_20170325_152954871_HDR.jpg
 
        [type] => image/jpeg
 
        [tmp_name] => /Applications/XAMPP/xamppfiles/temp/phpA49huQ
     )
)

Hello benanamen & psycho,
I want to reset the keys in the sub arrays & I don't want to reset the keys 'name', 'type', 'tmp_name', 'error' or 'size.' In this case,  the resulting $_FILES array can then be further processed, where the sub arrays are required ($_FILES['userfile']['name'][$num] for instance).

We didn't do much of anything with multi-dimensional arrays in the last PHP class I took. I've been studying, experimenting and testing multi-dimensional arrays for the last week or so, and have learned a bunch of neat tricks. This seems like it will be a useful tool for my bag of tricks.

 

Also, This is the way that the $_FILES array is set up, so, I want to be able to work with it as is - normally there will be many elements in this array.

If you could point me in the right direction, it will be very much appreciated.
Cheers,
Rick
