PHP FTP- functies
PHP FTP Inleiding
De FTP-functies geven client toegang tot bestandsservers via het File Transfer Protocol (FTP).
De FTP-functies worden gebruikt om verbindingen te openen, in te loggen en te sluiten, evenals om bestanden te uploaden, downloaden, hernoemen, verwijderen en informatie over bestanden op te halen van bestandsservers. Niet alle FTP-functies werken met elke server of geven dezelfde resultaten. De FTP-functies kwamen beschikbaar met PHP 3.
Als u alleen wilt lezen van of schrijven naar een bestand op een FTP-server, overweeg dan om de ftp://-wrapper te gebruiken met de bestandssysteemfuncties die een eenvoudigere en intuïtievere interface bieden.
Installatie
Om deze functies te laten werken, moet je PHP compileren met --enable-ftp.
De Windows-versie van PHP heeft ingebouwde ondersteuning voor deze extensie.
