Here's what I got for now:

<?php

echo "<div class='form-container'>";

if (isset($_POST['json'])){

$json = file_get_contents('php://input');
$json_data = json_decode($json,true);

// Display data
echo "post json: " . $_POST['json'] . "<br />";
echo "json: " . $json . "<br />";
echo "json data: " . $json_data . "<br />";
print_r($json_data);
} else {
echo "<form action='' method='post'>";
echo "<input type='file' id='json' name='json'>";
echo "<input type='submit'>";
echo "</form>";
}

echo "</div>";

?>
I made numerous attempts to obtain the provided data:
$json = file_get_contents($_FILES['json']['tmp_name']);
$json = file_get_contents($_POST['json']);

But nothing seems to function, and it appears that the file is always empty? When echoing $json, only the filename and no content are printed:
post json: 2022_7_30_12_24_PRACTICE.json
json: json=2022_7_30_12_24_PRACTICE.json
json data:
How do I download this file?
