Here’s one that accepts a variable number of rows and columns:

<?php
$rows = 9;
$cols = 9;
for ($row = 0; $row < $rows; $row++) {
  $num = ($row % $cols);
  for ($col = 0; $col < $cols; $col++) {
      if (++$num == $cols + 1) {
          $num = 1;
      }
      echo $num . ' ';
  }
  echo PHP_EOL;
}
