在str_repeat的每次迭代上运行rand（）函数

I'm trying to formulate some dummy data so that I can developed the front end of a html data table, to do this im writing the data out once and using str_repeat to out put it multiple times.

One of the features I'm incorporating in the front end is the ability to sort columns but to do that I need different data in each row. I planned to use rand() to assist with this part, but when I use it with the code block below, it generates a random number and the str_repeat outputs that 3 times..

Is there a simple way to get it to run the rand() func on each iteration of the str_repeat() func ?

$html = "
          <tr>
            <!-- Unit Price -->
              <td class='table-input input-number'>
                <input class='input-center' value='" . rand(10,200) . "'>
              </td>

            <!-- QTY -->
              <td class='table-input input-number'>
                <input class='input-center' value='" . rand(1,5) . "'>
              </td>
          </tr>";

        echo str_repeat($html,3);

The approach i ended up using is this below based on @Christoph's answer, with this approach it lets you input the html and the rand() values in a more straight forward fashion.

for($i = 0; $i < 3; $i++) {
   echo "<tr>
        <!-- Unit Price -->
          <td class='table-input input-number'>
            <input class='input-center'" . rand(1,5) . "'>
          </td>

        <!-- QTY -->
          <td class='table-input input-number'>
            <input class='input-center'" . rand(1,5) . "'>
          </td>
      </tr>";
}

No, you can't do it with str_repeat, because you have a fixed string, which is repeated. Use e.g.

$tmpl = "
  <tr>
    <!-- Unit Price -->
      <td class='table-input input-number'>
        <input class='input-center' value='%d'>
      </td>

    <!-- QTY -->
      <td class='table-input input-number'>
        <input class='input-center' value='%d'>
      </td>
  </tr>";
for($i = 0; $i < 3; $i++) {
    printf($tmpl, rand(10, 200), rand(1, 5));
}
