Answer 1

$city_names = array(
    'delhi',
    'mumbai',
    'kolkata',
    'chennai'
);
$city_query = http_build_query(array('city' => $city_names));

this will give you:

city[0]=delhi&city[1]=mumbai&city[2]=kolkata&city[3]=chennai

if you want to encode the brackets also then use the below code:

$city_query = urlencode(http_build_query(array('city' => $city_names)));

Output:

city%255B0%255D%3Ddelhi%26city%255B1%255D%3Dmumbai .....

Reference: http_build_query, urlencode
