CSV to JSON with PHP?

Question

I need to convert a CSV file to JSON on the server using PHP. I am using this script which works:

function csvToJSON($csv)          


        

Answer 1

I modified the answer in the question to use the first line of the CSV for the array keys. This has the advantage of not having to hard-code the keys in the function allowing it to work for any CSV with column headers and any number of columns.

Here is my modified version:

function csvToJson($csv) {
    $rows = explode("\n", trim($csv));
    $data = array_slice($rows, 1);
    $keys = array_fill(0, count($data), $rows[0]);
    $json = array_map(function ($row, $key) {
        return array_combine(str_getcsv($key), str_getcsv($row));
    }, $data, $keys);

    return json_encode($json);
}
