list files php from - create json file

Question

I want to create a php script that loads all my files (.pdf) from the 3 directory and create a json file.

I try this

$dir_2016 = \"./HCL/2016\";
$dir_201         


        

Answer 1

You should move your definition of $json_file to bottom as follow:

// ... get files code
$json_file = array(
    "2016" => $files_2016,
    "2015" => $files_2015,
    "2014" => $files_2014,
);
echo json_encode($json_file);

Because array is passing by value rather than passing by reference.

And, a better way to get files and sub-directories in a directory shallowly is use scandir, for example:

$files_2014 = array_slice(scandir('./HCL/files_2014'), 2)
