Fungsi PHP FTP
Pengenalan PHP FTP
Fungsi FTP memberikan akses klien ke server file melalui File Transfer Protocol (FTP).
Fungsi FTP digunakan untuk membuka, login, dan menutup koneksi, serta mengunggah, mengunduh, mengganti nama, menghapus, dan mendapatkan informasi tentang file dari server file. Tidak semua fungsi FTP akan bekerja dengan setiap server atau mengembalikan hasil yang sama. Fungsi FTP menjadi tersedia dengan PHP 3.
Jika Anda hanya ingin membaca dari atau menulis ke file di server FTP, pertimbangkan untuk menggunakan ftp:// wrapper dengan fungsi Filesystem yang menyediakan antarmuka yang lebih sederhana dan intuitif.
Instalasi
Agar fungsi-fungsi ini berfungsi, Anda harus mengkompilasi PHP dengan --enable-ftp.
PHP versi Windows memiliki dukungan bawaan untuk ekstensi ini.
