Every permutation of the alphabet up to 29 characters?

Question

I\'m attempting to write a program that will generate a text file with every possible permutation of the alphabet from one character up to twenty-nine characters. I\'ve chosen 2

Answer 1

Using PHP's Perl-style character incrementing.

set_time_limit(0);

$perm = 'A';
$endTest = str_repeat('Z',28).'A';
while ($perm != $endTest) {
    echo $perm++,"\n";
}

Run the script from the command line so you don't hit a webserver timeout; then sit back and wait a few years for it to complete
