web - Passing arrays in the URL - compatible with standars and all browsers -

i want to pass parameters of variable (and not post), comply seo-url-friendly methodology. let's that

$models = array( 5000, 6001, 7777);

so pass parameters this:

http://www.example.com/gallery-display/?models%5b%5d=5000&models%5b%5d=6001&models%5b%5d=7777

in way can retrieve values directly by:

 $models = $_get['models'];  print_r($models);

alternatives of using char separator pipeline "|" and

http://www.example.com/gallery-display/?models=5000|6001|7777

and retrieving data by

$models = explode("|", $_get['models']); print_r($models);

is not desired, reasons not confessable here.

is first 1 reliable method, comply standars , can trusted in decent modern web broswer?
