为了在PHP中创建所需的数组，需要对HTML输入字段进行哪些更改？

I've designed one HTML form as follows :

<form action="sample_test.php" method="post">
  <input type="text" name="fileName" value="8.png" id="fileName[]">
  <input type="text" name="fileLink" value="https://www.filepicker.io/api/file/zZ993JyCT9KafUtXAzYd" id="fileLink[]">

  <input type="text" name="fileName" value="2_OnClick_OK.jpg" id="fileName[]">
  <input type="text" name="fileLink" value="https://www.filepicker.io/api/file/1w3cKCW1TMmytb7md3XQ" id="fileLink[]">

  <input type="submit" name="Submit" value="Submit File">
</form>

Then the code in sample_test.php is as follows :

<?php
  print_r($_POST); die;
?>

The output I got is as follows : Array ( [fileName] => 2_OnClick_OK.jpg [fileLink] => https://www.filepicker.io/api/file/1w3cKCW1TMmytb7md3XQ [Submit] => Submit File )

But this is not the desired output. I want the desired output array to be printed in following manner:

Array
        (
            [8.png] => Array
                (
                    [0] => https://www.filepicker.io/api/file/zZ993JyCT9KafUtXAzYd
                )
            [2_OnClick_OK.jpg]
                (
                    [0] => https://www.filepicker.io/api/file/1w3cKCW1TMmytb7md3XQ
                )   

        )

For now I've just demonstrated with two elements only but in real situations hundreds of such elements could present on the form.

So what changes do I need to make in my HTML as well as PHP code? Please help me.

Thanks in advance.

What you ask is impossible by just modifying the HTML code, because you would like a value (of fileName) to become an index in the array you get. That's impossible, the index will always be the name of the input.

However, if you have a look here : POSTing Form Fields with same Name Attribute , you will be able to get arrays of fileName and fileLink, and I'm pretty sure you can do something from there.

A few things wrong, but you are close. Make the name field an array instead of the id - plus your ids need to be unique.

<input type="text" name="fileName[]" value="8.png" id="fileName1">
<input type="text" name="fileLink[]" value="https://www.filepicker.io/api/file/zZ993JyCT9KafUtXAzYd" id="fileLink1">

<input type="text" name="fileName[]" value="2_OnClick_OK.jpg" id="fileName2">
<input type="text" name="fileLink[]" value="https://www.filepicker.io/api/file/1w3cKCW1TMmytb7md3XQ" id="fileLink2">

Not tested, but should do the trick.
