Convert JSON to CSV and save from browser to computer - php

Question

I have this JSON:
{"data":[{"ID":1,"br":"1-2015","kupac":"ADAkolor","datum":"2015-05-19","rok":"2015-05-21","status":"placeno"},{"ID":2,"br":"2-2015","kupac":"Milenk","datum":"2015-05-27","rok":"2015-05-28","status":""}]}
How to convert this to CSV file or Exel XLS using php pdo?
Also in this example:
if (empty($argv[1])) die("The json file name or URL is missed\n");
$jsonFilename = $argv[1];
$json = file_get_contents($jsonFilename);
$array = json_decode($json, true);
$f = fopen('php://output', 'w');
$firstLineKeys = false;
foreach ($array as $line)
{
if (empty($firstLineKeys))
{
$firstLineKeys = array_keys($line);
fputcsv($f, $firstLineKeys);
$firstLineKeys = array_flip($firstLineKeys);
}
// Using array_merge is important to maintain the order of keys acording to the first element
fputcsv($f, array_merge($firstLineKeys, $line));
}
where I need to put my $jsonTable ?

Answer 1

Use JSON2CSV
A simple PHP script to convert JSON data to CSV
example usage:
php json2csv.php --file=/path/to/source/file.json --dest=/path/to/destination/file.csv
OR You can have it dump the CSV file relative to the PHP script:
php json2csv.php --file=/path/to/source/file.json

Answer 2

I am not sure about the pdo part, but to write it to a file you would do something like this
$json = '{"data":[{"ID":1,"br":"1-2015","kupac":"ADAkolor","datum":"2015-05-19","rok":"2015-05-21","status":"placeno"},{"ID":2,"br":"2-2015","kupac":"Milenk","datum":"2015-05-27","rok":"2015-05-28","status":""}]}';
$out = fopen('file.csv', 'w');
foreach(json_decode($json, true)['data'] as $key => $value) {
fputcsv($out, $value);
}
fclose($out);
