PHP fopen() Fungsi

Contoh

Buka file, baca baris - hingga EOF tercapai:

<?php
$file = fopen("test.txt", "r");

//Output lines until EOF is reached
while(! feof($file)) {
$line = fgets($file);
echo $line. "<br>";
}

fclose($file);
?>

Definisi dan Penggunaan

Fungsi fopen() membuka file atau URL.

Catatan: Saat menulis ke file teks, pastikan untuk menggunakan karakter akhir baris yang benar! Sistem Unix menggunakan \n, sistem Windows menggunakan \r\n, dan sistem Macintosh menggunakan \r sebagai karakter akhir baris. Windows menawarkan tanda terjemahan ('t') yang akan menerjemahkan \n ke \r\n saat bekerja dengan berkas. Anda juga dapat menggunakan 'b' untuk memaksa mode biner. Untuk menggunakan tanda ini, tentukan 'b' atau 't' sebagai karakter terakhir dari parameter mode.
