Name:
Category: \(^o^)/ Fun!
Body:

Writes characters to an image resource, and for each character, saves a .txt file with a '1' for black, and a ' ' for white pixels, so 'a.txt' becomes

1111
      11
       1
     111
  11   1
  1    1
  1   11
   111 1

<?php

$im = imagecreatetruecolor(10, 16);
$font = '/Library/Fonts/Andale Mono.ttf';

# Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 1);
$red   = imagecolorallocate($im, 255, 0, 0);
$blue   = imagecolorallocate($im, 0, 0, 255);

imagefill($im, 0, 0, $white);

$out = '';

foreach(str_split(' abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') as $char) {
  # apparently using negative colours makes them non-anti-aliased (aliased?) which is easier for drawing our ascii
  imagefttext($im, 12, 0, 0, 12, -$black, $font, $char);
  # prevent 'A.txt' overwriting 'a.txt'
  $filename = (! is_numeric($char) && (strtoupper($char) == $char)) ? $char.$char : $char;
  for($i=0;$i<16;$i++) {
    for($j=0;$j<10;$j++) {
      $x = imagecolorat($im, $j, $i);
      $out .= ($x == $black) ? '1' : ' ';
    }
    $out .= "\n";
  }
  file_put_contents("images/chars2/$filename.txt", $out);
  $out = '';
  imagefilledrectangle($im, 0, 0, 10, 16, $white);
}
imagedestroy($im);

And then, you can write a lil' commandline thing that takes text and ascify's it, like this:

#!/usr/bin/php
<?php

array_shift($argv);
echo aski(join(" ", $argv));

while ($foo = trim(fgets(STDIN))) {
  if (in_array($foo, array('quit', 'q', 'exit', 'bye'))) {
    echo "Bye!\n";
    die();
  }
  echo aski($foo);
}

nemo$ ./aski blaat

#         ###
#           #                             #

#    ##     #       #    #    #    #      #
##   #      #       #   ##    #   ##      #
# ###       ###      ### #     ### #      ####

(yes, I was bored.)
