This will get you started:


// Break 958469 into digits
$p1 = 9; $p2 = 5; $p3 = 8; $p4 = 4; $p5 = 6; $p6 = 9;

for($p = 0; $p < 10; $p++) echo sprintf("%d%d%d%d%d%d\
",$p, $p2,$p3,$p4,$p5,$p6);
for($p = 0; $p < 10; $p++) echo sprintf("%d%d%d%d%d%d\
",$p1,$p, $p3,$p4,$p5,$p6);
for($p = 0; $p < 10; $p++) echo sprintf("%d%d%d%d%d%d\
",$p1,$p2,$p, $p4,$p5,$p6);
for($p = 0; $p < 10; $p++) echo sprintf("%d%d%d%d%d%d\
",$p1,$p2,$p3,$p, $p5,$p6);
for($p = 0; $p < 10; $p++) echo sprintf("%d%d%d%d%d%d\
",$p1,$p2,$p3,$p4,$p, $p6);
for($p = 0; $p < 10; $p++) echo sprintf("%d%d%d%d%d%d\
",$p1,$p2,$p3,$p4,$p5,$p );

You can generalize it and wrap it in a function.

Challenge accepted :slight_smile:


$x = 958469;
xx($x);
function xx($x = 958469)
{
  $x = (string) $x;
  $y = str_split($x);

  echo '<br />';
  foreach($y as $id => $val)
  {
    echo '<br />'; // .$id, ', ' .$val;
    for($i3=0; $i3<10; $i3++)
    {
      if($id > 0) // Miss the first item
      {
          echo substr($x, 0, $id);
      }    
      echo $i3 .substr($x, 1+$id);
     echo ($i3 < 9) ? ', &nbsp;  ' : NULL;
    }
  }
}

Output

058469, 158469, 258469, 358469, 458469, 558469, 658469, 758469, 858469, 958469

Mr. John_Betong

Thanks for the reply, your code is very much near what i wanted. But your code prints 60 values in which 5 values are duplicate and one principal value for which we are generating similar number. In the result there should be 54 unique value excluding the main value.

I will be grateful if you can help me to create code to get this result.

If we are to “help” you and not “do it for you” you can help us by showing what you have tried and are having trouble with and don’t understand.
I love homework problems as much as the next guy, but my school days have long past.
