Question

Ok I have an associative array contains data that should be downloaded in a file and then imported later to use the same data later.

it looks like this (only some keys contain arrays):

array(
   'id1' => 'Data1',
   'id2' => 'Data2',
   'id3' => 'Data3',
   'id4' => 'Data4',
   'id5' => array(
               'id1' => 'Data1',
               'id2' => 'Data2',
               'id3' => 'Data3'
        )

);

so what is the best way to do this ?

Answer 1

Try serialize:

file_put_contents($filename, serialize($array));

And to read:

$array = unserialize(file_get_contents($filename));
