file put contents with array

Question

I am using file_put_contents($file, $data); function for putting contents in file, because these files are created on fly with name of sessions, $data is an multi-dimensional array, when i am echoing array it prints out fine but in file no contents get recorded except the word Array

What should i do or is there any other function which automatically creates the file and records the data (array)?

Thank You.

Answer 1

You want to serialize() the array on writting, and unserialize() after reading the file.

$array = array('foo' => 'bar');
file_put_contents('foo.txt', serialize($array));
$array = unserialize(file_get_contents('foo.txt')));

Oh, and I really don't now how you echo'd your array, but echo array('foo' => 'bar'); will always print Array.
