Perl[]
#!/usr/bin/perl
# open file
open(FILE, "data.txt") or ("open file");
# read file into an array
@data = <FILE>;
close(FILE);

Reading from file:
if ( !($fp = @fopen('myfile.txt', 'r')) ) // r = read mode
myfile.txt
while (/line = fgets(?+%fp, 4096)) { // reads 4096 bytes
. '<br>';
}
fclose($fp); // closes the file
Overwriting a file:
$fp = fopen('myfile.txt', 'w'); // r = write mode
fputs($fp, 'Hello World!'; // writes 'Hello World!'
fclose($fp);
Adding 1 line to a file:
$fp = fopen('myfile.txt', 'a'); // a = append mode
fputs($fp, 'Hello World!'; // appends 'Hello World!'
fclose($fp);
Python[]
f = open(filename, 'r') data = f.read() f.close()
