Remove encoding characters from http_build_query - php

Question

I'm trying to get a JSON Array of Objects and turn into a HTTP query.
The JSON is like this:
[
{"name": "Silvia"},
{"age": 24}
]
I need to turn into this:
?name=Silvia&age=24
I'm trying to use `http_query_params(), but its returning the query like this:
?0%5Bname%5D=Silvia&1%5Bage%5D=24
I tried to use urldecode() but not helped...
Here is my full code:
$jsonArray = json_decode($data['filters']);
$query = http_build_query($jsonArray, null, '&');
$url = $endpoint."?".$query;

Answer 1

Instead of building the query string manually let's use http_build_query() as we should. But first, let's flatten the original array;
$jsonString = '[
{"name": "Silvia"},
{"age": 24}
]';
$jsonArray = json_decode($jsonString, true); // true flag converts to array instead of object
$assoc_array = array();
foreach($jsonArray AS $arr){
foreach($arr AS $key => $val) {
$assoc_array[$key] = $val;
}
}
This returns;
Array
(
[name] => Silvia
[age] => 24
)
Now make the query string;
$queryString = http_build_query($assoc_array);
echo urlencode($queryString); // you can actually skip this
which returns;
name%3DSilvia%26age%3D24
As you can see in this example
This is much more "portable" and you can make a function out of the array flattening method demonstrated.

This will be the solution to your problem :)
$items = json_decode('[
{"name": "Silvia"},
{"age": 24}
]');
$count = 1;
$string = '';
foreach($items as $item)
{
foreach($item as $key => $val)
{
$char = ($count == 1) ? "?" : "&";
$string .= $char . urlencode($key) . "=" . urlencode($val);
$count++;
}
}
echo $string;
This will be ?name=Silvia&age=24
