http_build_query

  • This function’s solution will only work within the context of the Rails framework.

    PHP’s http_build_query function provides a convenient way to generate URL-encoded query strings from associative arrays.

    PHP

    $data = array('foo' => array('bar' => 'baz'));
$query = http_build_query($data);
var_export($query);
 
//=> 'foo%5Bbar%5D=baz'

    In Rails, we can use ActiveSupport’s Hash#to_query method.

    Rails

    data = {:foo => {:bar => 'baz'}}
p data.to_query
 
#=> "foo%5Bbar%5D=baz"
