Building strings

[The Little Guy]

I was thinking how can I make a script that will build strings incrementing through each letter starting with "a" and ending with "zzzzzz" or what ever ending length I want such as 12.

 

So if your were to output everything, you could find the words:

"dog"

"spider"

"superman"

"hippo"

etc

 

What would be the best way to do this, so I don't have to have a loop that is 500 blocks deep to show a word that is 500 letters

 

example

a

...

z

aa

ab

ac

...

az

ba

bb

bc

...

...

aaa

aab

aac

Sorry, but its not at all clear what your wanting to do.

[The Little Guy]

Maybe this example will help. Just follow the pattern:

a
b
c
d
e
f
g
h
i
j
k
l
m
n
o
p
q
r
s
t
u
v
w
x
y
z
aa
ab
ac
ad
ae
af
ag
ah
ai
aj
ak
al
am
an
ao
ap
aq
ar
as
at
au
av
aw
ax
ay
az
ba
bb
bc
bd
be
...
aaa
aab
aac
aad
aae
aaf
....
aba
abb
abc
abd
.....
aaaa
aaab
aaac
....
abaa
abab
abac
....

 

basically it walks its way through every string combination possible (using a looping method) with a string no longer than the defined max length and displaying them all on the screen (CLI).

 

so, if there was a string max length of 10 and only using a-z lowercase there is a maximum of 141,167,095,653,376 combinations (26^10)

The computer running the program will be dead before it finishes. You've got the number 9and obviously the time), work out how long it will take to finish if 1 iteration took 1 hundredth of 1 second.

 

What exactly do you hope to achieve by doing this?

[MMDE]

poor whatever he outputs this to... and sounds like bruteforce of some sort to me o.O

[The Little Guy]

What exactly do you hope to achieve by doing this?

 

Not really anything, I just want to make something like this.

[QuickOldCar]

Well I could see wanting to generate maybe words or numbers at random. But like the above persons said expect the server to just puke,exhaust, time out or w/e else with trying that many.

 

It's just too many to produce.

 

Now maybe if did in itsy bitsy steps and started saving either to text files or a database, then maybe you can.

 

I sat here writing up something you can at least play with to try to suit your needs.

Maybe it can give you some ideas, the end result I limited it to just showing words with length of 3, so if changed that to 2 or 1 would see the others.

 

<?php
$positions = 1;
$i = 0;
for ($i = 0;$i<$positions;$i++) {
  foreach ( range('a','z') as $alphabet) {
  $the_alphabet[] =  $alphabet;
}

}
if (++$i == $positions) break;

foreach($the_alphabet as $k1 =>$v1){
    $words[]=$v1;
    foreach($the_alphabet as $k2 => $v2){
        $words[]=$v2;
        $words[]="$v1$v2";
        foreach($the_alphabet as $k3 => $v3){
            $words[]=$v3;
            $words[]="$v1$v2$v3";
            $words[]="$v1$v3$v2";
        }
    }
}
$words = array_unique($words);
sort($words);
foreach($words as $word){
$word_length = strlen($word);
if ($word_length == 3) { //try 2 or 1
    echo "$word<br>";
}
}
?>

for($i= 'a'; $i <'zz'; $i++) echo $i;

not tested

[The Little Guy]

for($i= 'a'; $i <'zz'; $i++) echo $i;

haha! I thought you were being sarcastic but it actually works!

[Pikachu2000]

I never would have thought that would work either. Interesting. That could come in handy in the future.

[ignace]

for($i= 'a'; $i <'zz'; $i++) echo $i;

 

Haha! If that only really worked

 

Try:

for($i= 'a'; $i < 'z'; $i++) echo $i;

 

And now run:

for($i= 'a'; $i <= 'z'; $i++) echo $i;

 

Produces suddenly the double number of results (and orders incorrectly) The answer lies in it's implementation

[Anti-Moronic]

or maybe:

 

for($color = 'white'; $color < 'black'; $color++) echo $color;

[BlueSkyIS]

for($i= 'a'; $i <'zz'; $i++) echo $i;

Now explain why it does this

[The Little Guy]

I decided to try and throw some symbols, upper case letters and lower case letters in there as well... Doesn't work too well:

$start = 32;
$fin = 126;
$depth = 1;

$i = $start;
while(true){
$opt = '';
for($d=0;$d<=$depth;$d++){
	$opt .= chr($i);
	if($d == $depth){
		$depth++;
		break;
	}
}
echo $opt."\n";
$i++;
}

 

Oh, and btw if you don't want it to end:

$i = 'a';
while($i){
echo $i."\n";
$i++;
}

[QuickOldCar]

Well here's the best way by far.

I guess can even do sets of the 26 letters as well, something like show single letters, then show 2 letters, then show 3 letters and so on , but just do them in ranges so don't have to produce what you don't need.

<?php
$how_many_you_want = 50000;//each number will add an extra line/sequential alphabet string

function seqAlphabet($numbers)
{
  $alphabet = '';
  while($numbers >= 1) {
    $numbers = $numbers - 1;
    $alphabet = chr(($numbers % 26)+97) . $alphabet;
    $numbers = $numbers / 26;
  }
  return $alphabet;
}
$string_position = range('1',$how_many_you_want);
foreach ($string_position as $position) {
echo seqAlphabet($position) . "<br />";
}
?>

 

[The Little Guy]

Using this:

$i = 'a';
$c = 1;
while(true){
echo $c.'. '.$i."\n";
if($i == 'ryan')
	exit;
$i++;
$c++;
}

I am totally baffled at what is going on. To be honest I can't even understand a-z, but a-zz, a-zzzzzz?? what the hell is going on? :S

Using this:

$i = 'a';
$c = 1;
while(true){

if($i == 'ryan')

$c++;
