You can use the following:

<?php
$_POST["number"] = 10;
$row_num = array();
for ($row = 1; $row <= $_POST["number"]; $row++)
{
    $count = 0;
    for ($col = 1; $col <= ($row >= ($_POST["number"]/2) ? ($_POST["number"]+1)- $row : $row); $col++)
    {
        $count++;
        echo '* ';
    }
    echo "<br>";
    array_push($row_num, $count);
}
print_r ($row_num);
?>
