[SOLVED] Stop and Continue

[nuxy]

Well, I've made a script that makes random words(letter sequences), but my here is my problem.

It's not really a problem, just a feature I want to enhance.

 

The script will make millions/billions of letter sequences, but that takes a long time.

What I want to do is to be able to stop the script, and then continue it at a later point, from that original point I stopped it.

Say it came to the letter sequence "as1s" and then I stop it, the next time it should go on from "as1s" and make "as1t" and so forth.

 

Here is my current script, a bit messy, but should be doable.

function auto() {
global $mysql;
echo 'Beginning to add hashes..<br><form method="post" action="?auto">
<input type="submit" value="Show No Output" name="blah"></form><br><br>';
$chars = '1234567890abcdefghijklmnopqrstuvwxyz';
for($next[0]=0;$next[0]<=(strlen($chars)-1);$next[0]++) {
	for($next[1]=0;$next[1]<=(strlen($chars)-1);$next[1]++) {
	 for($next[2]=0;$next[2]<=(strlen($chars)-1);$next[2]++) {
	  for($next[3]=0;$next[3]<=(strlen($chars)-1);$next[3]++) {
	   for($next[4]=0;$next[4]<=(strlen($chars)-1);$next[4]++) {
	    for($next[5]=0;$next[5]<=(strlen($chars)-1);$next[5]++) {
	     for($next[6]=0;$next[6]<=(strlen($chars)-1);$next[6]++) {
	      $string = '';
	      if ($next[0]) $string .= $chars[$next[0]];
	      if ($next[1]) $string .= $chars[$next[1]];
	      if ($next[2]) $string .= $chars[$next[2]];
	      if ($next[3]) $string .= $chars[$next[3]];
	      if ($next[4]) $string .= $chars[$next[4]];
	      if ($next[5]) $string .= $chars[$next[5]];
	      if ($next[6]) $string .= $chars[$next[6]];
                            // otehr processing stuff not rellative here..
	    }
	   }
      }
     }
    }
   }
  }
}

 

Also, if anyone knows how to optimize, well, not really optimize, but another way to do this aswell, I would appreciate it.

Anyone have an idea how I can make this feature?

 

Thank you in advance...

What I do is database all the phrases you made, of course this reslts in having to recheck the table on each itteration for repeats

[nuxy]

That is my problem, i'm already checking the hashes against a database.

But anyways, I've been working on it, founda partial solution.

 

function auto() {
global $mysql;
$chars = '1234567890abcdefghijklmnopqrstuvwxyz';
echo 'Loading Config: ';
$datafeed = file_get_contents('stats.ini');
$datafile['new'] = split("\n", $datafeed);
foreach($datafile['new'] as $varline) {
	$vars = split(' = ', $varline);
	$var[$vars[0]] = $vars[1];
}
$pre[0] = $var['next[0]'];
$pre[1] = $var['next[1]'];
$pre[2] = $var['next[2]'];
$pre[3] = $var['next[3]'];
$pre[4] = $var['next[4]'];
$pre[5] = $var['next[5]'];
$pre[6] = $var['next[6]'];
echo 'Loaded<br><pre>';
print_r($pre);
echo '</pre><br><br>';
for($next[0]=$pre[0];$next[0]<=(strlen($chars)-1);$next[0]++) {
	for($next[1]=$pre[1];$next[1]<=(strlen($chars)-1);$next[1]++) {
	 for($next[2]=$pre[2];$next[2]<=(strlen($chars)-1);$next[2]++) {
	  for($next[3]=$pre[3];$next[3]<=(strlen($chars)-1);$next[3]++) {
	   for($next[4]=$pre[4];$next[4]<=(strlen($chars)-1);$next[4]++) {
	    for($next[5]=$pre[5];$next[5]<=(strlen($chars)-1);$next[5]++) {
	     $fp = fopen('stats.ini', 'w');
	     $datafeed = file_get_contents('stats.ini');
	     $datafile['new'] = split("\n", $datafeed);
	     foreach($datafile['new'] as $varline) {
			$vars = split(' = ', $varline);
			$var[$vars[0]] = $vars[1];
		 }
		 $var['next[0]'] = (empty($var['next[0]'])) ? 0 : $var['next[0]'];
		 $var['next[1]'] = (empty($var['next[1]'])) ? 0 : $var['next[1]'];
		 $var['next[2]'] = (empty($var['next[2]'])) ? 0 : $var['next[2]'];
		 $var['next[3]'] = (empty($var['next[3]'])) ? 0 : $var['next[3]'];
		 $var['next[4]'] = (empty($var['next[4]'])) ? 0 : $var['next[4]'];
		 $var['next[5]'] = (empty($var['next[5]'])) ? 0 : $var['next[5]'];
		 $var['next[6]'] = (empty($var['next[6]'])) ? 0 : $var['next[6]'];
		 foreach($var as $key => $vl) fputs($fp, $key . " = " . $vl . "\n");
		 fclose($fp);
	     for($next[6]=$pre[6];$next[6]<=(strlen($chars)-1);$next[6]++) {
	      $string = '';
	      if ($next[0]) $string .= $chars[$next[0]];
	      if ($next[1]) $string .= $chars[$next[1]];
	      if ($next[2]) $string .= $chars[$next[2]];
	      if ($next[3]) $string .= $chars[$next[3]];
	      if ($next[4]) $string .= $chars[$next[4]];
	      if ($next[5]) $string .= $chars[$next[5]];
	      if ($next[6]) $string .= $chars[$next[6]];
	      // not relevant to the topic
	    }
	   }
      }
     }
    }
   }
  }
}

 

Still debugging, so I'm still open to ideas..

try

<?php
function my_next($a, $car = '1234567890abcdefghijklmnopqrstuvwxyz'){
$num = strlen($car);
$add = 1;
$out = '';
for ($i = strlen($a); $i > 0;){
	$x = strpos($car, $a[--$i]) + $add;
	$out = $car[$x % $num].$out;
	$add = floor($x / $num);
}
if ($add) $out = $car[0].$out;
return $out;
}

$start = 'zx';
for ($i = 0; $i <20; $i++){ // or some other condition
echo $start = my_next($start),"\n";
}
// remember last $start and next time use it
?>

I got my script working, it is actaully very precise now.

Thanks everyone..
