Matching input text and input file to each other in PHP

I have a dynamic form that allows someone to add a row that has 2 input types. The first one can be an image or text field and the second one is always a text field. I need the first field to be tied with the second field in post. So I can add to a database field1A and field2A in the same row. The issue is that a file upload is in its own array so I can’t just loop through my text array and know that the image is tied to that text field.

<input type="text" name="field1[]">

If I loop through my field1[] array and get the index it will be different than my $_Files and I don’t know where in the array my files are.

        Field1  |  Field2
    -----------------------
 A      text    |  text
    -----------------------
 B  file upload |  text
    -----------------------

Your best bet, like @fubar said would be to set the keys while you are rendering the html :

<input type="text" name="field[0][0]">
<input type="file" name="field[1][0]">

<input type="text" name="field[0][1]">
<input type="text" name="field[1][1]">

<input type="text" name="field[0][2]">
<input type="file" name="field[1][2]">

Then you could loop in PHP like this :

foreach($_POST['field'][0] as $key => $value) {
    $field1 = $_POST['field'][0][$key];
    $field2 = $_POST['field'][1][$key] ?? $_FILE['field'][1][$key];
}
