build_query()

build_query() — Builds a URL query based on an associative or indexed array. This is a convenient function for easily building URL queries. It sets the separator to ‘&’ and uses the _http_build_query() function. Unlike PHP’s native http_build_query(), this function does NOT URL-encode the keys or values. Callers are responsible for encoding values beforehand with urlencode() or rawurlencode(), or late-escaping the output with esc_url() before use.

Inputs: $data (array): Array of key/value pairs to build the query from.

Returns string: Query string, without URL encoding applied.
