get PHP $_FILES array name

Question

I have a html form sending to php script with "post" method (no ajax involved).

In the form i have some type="file" fields.

Now in my php script i have a php foreach loop looping through the sent files:

foreach($_FILES as $file) {
// Some checks and actions.
}

In that loop i want to be able to use the current file array name (which is equal to the name attribute of the upload filled it was uploaded from of course), so i treid:

foreach($_FILES as $file) {
// Some checks and actions.
print ($file);
}

But that's just echoing "Array".

Important note: My $_FILES array is structured like that:

Array
(
    [_pf_photo1] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 0
        )

    [_pf_photo2] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 0
        )

    [_pf_photo3] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 0
        )

    [_pf_photo4] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 0
        )

    [_pf_photo5] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 0
        )

    [selfimage] => Array
        (
            [name] => IMG_9785.JPG
            [type] => image/jpeg
            [tmp_name] => /tmp/phpWMOKhn
            [error] => 0
            [size] => 104221
        )

)

($_FILES can be structured another way, so to make things clear). so in that example what i want to get in the loop (for the array name part) is:

_pf_photo1, _pf_photo2, _pf_photo3, _pf_photo4, _pf_photo5, selfimage

use print_r or var_dump for debugging. print works only with strings. — colburton

That is already suggested in the @George shaw's answer. see comment there. — mondi

Will sharing the form code will be helpful even thought the print_r($_FILES) is shared? — mondi

This may be what you're looking for if I am understanding your problem correctly.

foreach($_FILES as $key => $value) {
    echo $key;
}

The only other way I can understand this question is if you're incorrectly using print. To print an object/array out with all of its data you can use var_dump instead of print.

it guess it will work but then i won't be able to use things like $file[name] in the middle of the loop. am i right?

You will definitely be able to access array values inside of that loop. In my example it would look like this echo $value['name']; because $value references an array within $_FILES whereas $key just references the name of the array.

Great! Thanks! finally got that (sort of...:)

I hope you are looking to extract your keys

foreach ($_FILES as $key => $file) { 
  echo $key; // print your array key
  echo $file['name']; // print your name inside that array
}
