PHP two Dimensional array in to file -

can please tell me how can save 2 dimensional array in text file

if have array unknown number of elements in index value:

$two_darray[unknown][unknown]; 

actually, @brad's , @hilmi's answers correct, i'm not sure using json advice.

you can choose

json

write: file_put_contents('somefile.json', json_encode($two_darray));

read: $two_darray = json_decode(file_get_contents('somefile.txt'));

xml

look this answer

serialized data

write: file_put_contents('somefile.txt', serialize($two_darray));

read: $two_darray = unserialize(file_get_contents('somefile.txt'));

csv (to use ms excel or db)

$handler = fopen('somefile.csv', 'w+'); foreach ($two_darray $one_darray) {     fputcsv($handler, $one_darray); } 

read fgetcsv

and sqlite

$db = new sqlitedatabase('somefile.sqlite'); foreach ($two_darray $one_darray) {     $db->query("insert `mytable` values (".implode(',', $one_darray).")"); } 

read: $two_darray = $db->sqlite_array_query("select * mytable");
