how to save data to variable from data array

Question

I get this data array from form and I need to save this array data to five different variables, so how I do,
this is filled with images data

 +files: Symfony\Component\HttpFoundation\FileBag {#61 ▼
    #parameters: array:1 [▼
      "img" => array:5 [▼
        0 => Symfony\.... {#42 ▶}
        1 => Symfony\....{#43 ▶}
        2 => Symfony\....{#44 ▶}
        3 => Symfony\.... {#45 ▶}
        4 => Symfony\....{#46 ▶}
      ]
    ]

I need to add data to these variables

$img1 = 0
$img2 = 1
$img3 = 2
$img4 = 3
$img5 = 4

I think you need to learn how to use arrays or the corresponding class methods rather than extracting to variables. Variables called img1, 2... is usually indication that arrays should be used. — Nigel Ren

You can use ${$variable_name} syntactic sugar from php to assign or get variable from using string as variable name

$img0 = null; $img1 = null; $img2 = null; $img3 = null; $img4 = null; $img5 = null; 

foreach($files['img'] as $key => $file){
    $varname = 'img' . $key; //img1 , img2 , img3 ...

    ${$varname} = $key; // $img1 = 0, $img1 = 1, $img3 = 1;
}

I think this code will be solution for you

Maybe using 'list ()' you can achieve what you want.

PHP: Returning values #Example2

list($img1, $img2, $img3, $img4, $img5) = array_values($files['img']);

// $img1 the first image
// $img2 the second image
// etc
