[Solved] How to make a graphic using numbers with PHP [closed]

Question

try something like this.

$set = array( 7, 8 );
echo '<pre>';
foreach( $set as $number ){
  //assuming number is your INT
  $array = range( 1, $number );
   while( count( $array ) ){
       echo "\n";
       var_export( $array );
       //remove first element
       array_shift( $array );
       //remove last element
       array_pop($array);
   }
}

Outputs:
For 7

array (
  0 => 1,
  1 => 2,
  2 => 3,
  3 => 4,
  4 => 5,
  5 => 6,
  6 => 7,
)
array (
  0 => 2,
  1 => 3,
  2 => 4,
  3 => 5,
  4 => 6,
)
array (
  0 => 3,
  1 => 4,
  2 => 5,
)
array (
  0 => 4,
)

For 8

array (
  0 => 1,
  1 => 2,
  2 => 3,
  3 => 4,
  4 => 5,
  5 => 6,
  6 => 7,
  7 => 8,
)
array (
  0 => 2,
  1 => 3,
  2 => 4,
  3 => 5,
  4 => 6,
  5 => 7,
)
array (
  0 => 3,
  1 => 4,
  2 => 5,
  3 => 6,
)
array (
  0 => 4,
  1 => 5,
)

I’ll leave it to you to build a multi-dimensional array out of that.

If you just want the output, than use echo implode(' ', $array ); in place of var_export(). Such as this:

$set = array( 7, 8 );
echo '<div style="text-align:center">';
foreach( $set as $number ){
      //assuming number is your INT
      $array = range( 1, $number );
       while( count( $array ) ){
           echo implode(' ', $array );
           //remove first element
           array_shift($array);
           //remove last element
           array_pop($array); 
           echo '<br>';
       }
       echo '<br>';
 }
 echo '</div>';

Outputs:

 1 2 3 4 5 6 7
   2 3 4 5 6
     3 4 5
       4

 1 2 3 4 5 6 7 8
   2 3 4 5 6 7
     3 4 5 6
       4 5
