I suggest to use JavaScript in order to manipulate the DOM. However you can do it with PHP as well:

First you need to know how many input:

<form action="" method="post">
 <select name="howManyInput">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
 </select>
</form>

In the 'action' page you get the value of 'howManyInput':

<?php 
 $howMany = $_POST['howManyInput'];
?>

Then you print the input you need in a 'for' loop:

<form action="" method="post">
<?php
 for( $i=0; $i<$howMany; $i++ ){
   echo '<input name="inputName'.$i.'" >';
   // if you need more the 1 input for '$howMany' echo it here
 }
?>
</form>

The first form take you to the page where the user can insert data. In that page you print as many input the user select in the previous page.

When the second form is submitted it goes to a page that receive all data.
