Note

Notă:

Aceasta este o variabilă 'superglobală', sau globală automată. Aceasta pur și simplu înseamnă că ea este disponibilă în toate circumstanțele pe parcursul script-ului. Nu este nevoie de a scrie global $variable; pentru a o accesa din funcții sau metode.

Cookies with the same name the first cookie is used. Clients will send cookies with longer path before cookies with shorter path. This comes from RFC 6265 which says "Cookies with longer paths are listed before cookies with shorter paths.". So you get the best matching cookie for your current request.
