Example
The http_build_query() will create a query string from an array or object. These strings can be appended to a URL to create a GET request, or used in a POST request with, for example, cURL.
$parameters = array(
'parameter1' => 'foo',
'parameter2' => 'bar',
);
$queryString = http_build_query($parameters);
$queryString will have the following value:
parameter1=foo¶meter2=bar
http_build_query() will also work with multi-dimensional arrays:
$parameters = array(
"parameter3" => array(
"sub1" => "foo",
"sub2" => "bar",
),
"parameter4" => "baz",
);
$queryString = http_build_query($parameters);
$queryString will have this value:
parameter3%5Bsub1%5D=foo¶meter3%5Bsub2%5D=bar¶meter4=baz
which is the URL-encoded version of
parameter3[sub1]=foo¶meter3[sub2]=bar¶meter4=baz
