Append Data to a .JSON File with PHP: Achieving Incremental IDs and Preserving JSON Structure
To append data to a .JSON file with PHP, a common approach is to read the existing JSON content, append the new data, and then rewrite the updated content to the file. This ensures that the JSON structure is preserved and that new records are added with appropriate identifiers.

<code class="php">$data = $_POST['data']; $fileContents = file_get_contents('results.json'); $tempArray = json_decode($fileContents); $tempArray[] = $data; $jsonData = json_encode($tempArray); file_put_contents('results.json', $jsonData);</code>
