displaying array

Good day.

Am displaying array in five columns and I need to push value to the last if values having specified key arrived at last.

<?php

$say = array("1","2","3","4","m"=>"5","s"=>"6","7","8","9","10","11","12");

$columns = 5;

for ($p=0; $p <count($say); $p++) {


    if ($p==0) { 
            print "<table><tr>";
    } elseif ($p%$columns == 0) { 
            print "<tr>";
    }

    print "<td>".htmlspecialchars($say[$p])."</td>";


    if (($p+1)%$columns == 0) { 
            print "</tr>";
    }
    if ($p==count($say)-1) { 
            $empty = $columns - (count($say)%$columns) ;
            if ($empty != $columns) {
                    print "<td colspan=$empty>&nbsp;</td>";

            print "</tr></table>";
    }
  }
  ?>

I used this code to display in five columns

Based on the comments below, this should solve your problem:

<?php

// Returns TRUE is the value is non-numeric otherwise FALSE.
function is_non_numeric($value)
{
  return ! is_numeric($value);
}

// The number of columns
$columns = 5;

// The data
$data = array('1', '2', '3', '4', 'm' => '5', 's' => '6', '7', '8', '9', '10', '11', '12');

// Chunk the data into rows of {$columns} columns.
$rows = array_chunk($data, $columns, TRUE);

// Output the table if there are rows.
if ( ! empty($rows) )
{
  echo '<table>';

  // Loop through each rows.
  foreach ( $rows as $row )
  {
    // Find all non-numeric keys, if any.
    $non_numeric_keys = array_filter(array_keys($row), 'is_non_numeric');

    // Loop through each non-numeric keys if one or more were found.
    if ( ! empty($non_numeric_keys) )
      foreach ( $non_numeric_keys as $offset => $non_numeric_key )
      {
        // Skip this one of the non-numeric key isn't the first or last of the row.
        if ( $offset != 0 && $offset != ( $columns - 1 ) )
          continue;

        // Remove the value with a non-numeric key from the row.
        $value = array_splice($row, $offset, 1);

        // Randomly select where the value will be re-inserted.
        $random = rand(1, ( $columns - 2 ));

        // Re-insert the value with a non-numeric key.
        array_splice($row, $random, 0, $value);
      }

    echo '<tr>';

    // Loop through each columns.
    foreach ( $row as $index => $column )
      echo '<td>' . $column . '</td>';

    // If the row doesn't have {$columns} columns add one that spans the number of missing columns.
    if ( ( $colspan = $columns - count($row) ) != 0 )
      echo '<td colspan="' . $colspan . '">&nbsp;</td>';

    echo '</tr>';
  }

  echo '</table>';
}
