function parse_query in Auth0 Single Sign On 8.2

Parse a query string into an associative array.

If multiple values are found for the same key, the value of that key value pair will become an array. This function does not parse nested PHP style arrays into an associative array (e.g., foo[a]=1&foo[b]=2 will be parsed into ['foo[a]' => '1', 'foo[b]' => '2']).

Parameters

string $str Query string to parse:

int|bool $urlEncoding How the query string is encoded:

Return value

array
