java - send String[] b httprequest and get in php b $_GET -

i want send string[] http request , values in php $_get method.
total number of values in string[] variable.
have tried far:

list<namevaluepair> params = new arraylist<namevaluepair>(); string[] dropdowns = {"1st item","2nd item","3rd item","4th item"}; (int = 0; < dropdowns.length; i++) { params.add(new basicnamevaluepair("pid", dropdowns[i])); } 

in php want values , query based on them.

$pid = $_get['pid']; 

and use them like:

$result = mysql_query("select *from apps pid[0] = $pid" , pid[1] = $pid"  , ...); 

but know way wrong. how can that?

this

$result = mysql_query("select *from apps pid[0] = $pid" , pid[1] = $pid" , ...);  

is wrong , unsafe. (columns wrong syntax, sql injection, wrong quotation, wrong sql syntax,...)

must like

$result = mysql_query("             select * apps pid             in(" . implode(',', mysql_real_escape_string($pid)) . ")           ");
