PHP File Handling
Dalam PHP, fungsi fopen() digunakan untuk membuka file.
Membuka File
Program16-1.php
<html> <body> <?php $file=fopen("welcome.txt","r"); ?> </body> </html> |
Mode pembukaan file
Mode | Keterangan |
r | Read only. Starts at the beginning of the file |
r+ | Read/Write. Starts at the beginning of the file |
w | Write only. Opens and clears the contents of file; or creates a new file if it doesn't exist |
w+ | Read/Write. Opens and clears the contents of file; or creates a new file if it doesn't exist |
a | Append. Opens and writes to the end of the file or creates a new file if it doesn't exist |
a+ | Read/Append. Preserves file content by writing to the end of the file |
x | Write only. Creates a new file. Returns FALSE and an error if file already exists |
x+ | Read/Write. Creates a new file. Returns FALSE and an error if file already exists |
Catatan: Jika fopen() tidak dapat membuka file, maka akan mengembalikan nilai 0 (false).
Program16-2.php
<html> <body> <?php $file=fopen("welcome.txt","r") or exit("Unable to open file!");
?> </body> </html> |
Menutup File
Program16-3.php
<?php $file = fopen("test.txt","r"); //some code to be executed fclose($file); ?> |
Memeriksa EOF (End Of File)
Catatan: Kita tidak dapat membaca file yang terbuka dalam mode w, a, dan x!
if (feof($file)) echo "End of file"; |
Membaca file baris per baris (fgets())
Program16-4.php
<?php $file = fopen("welcome.txt", "r") or exit("Unable to open file!"); //Output a line of the file until the end is reached while(!feof($file)) { echo fgets($file). "<br />"; } fclose($file); ?> |
Membaca file karakter per karakter (fgetc())
Program16-5.php
<?php $file=fopen("welcome.txt","r") or exit("Unable to open file!"); while (!feof($file)) { echo fgetc($file); } fclose($file); ?> |
