This should do it:  (going to test it now, will update if it changes)
<?php

$lines = (isset($_POST['nextlines']) ? $_POST['nextlines'] : 1;

$form = "<form action=\"" . $PHP_SELF . "\" METHOD=\"POST\">";
$form .= 'Text line: <input name="textline" type="text" /><br />';
$form .= 'Number of new lines: <input name="nextlines" type="text" size="4" /><br />';
$form .= "Additional Lines Below<hr />";
for($x=0;$x<=$lines;$x++) {
  $form .= 'Line #: ' . $x + 1 . " <input type="text" name="mytext[' . $x . ']" />';
 }
 
 ?>

Open in new window

Here is the non buggy code:
<?php

$lines = (isset($_POST['nextlines'])) ? $_POST['nextlines'] : 1;

$form = "<form action=\"" . $PHP_SELF . "\" METHOD=\"POST\">";
$form .= 'Text line: <input name="textline" type="text" /><br />';
$form .= 'Number of new lines: <input name="nextlines" type="text" size="4" /><br />';
$form .= "Additional Lines Below<hr />";
for($x=0;$x<$lines;$x++) {
  $form .= 'Line #: ' . ($x + 1) . ' <input type="text" name="mytext[' . $x . ']" />';
 }
$form .= "<input type=submit value=Go></form>";
 echo $form;
?>

Open in new window

To access variables in the dynamically created lines, in php you do this:

$MyNewLines = $_POST['mytext'];

foreach($MyNewLines as $index => $value) {
 echo "Key # $index = $value <br />";
}

Or  you can access like

$line2 = $MyNewLines[2];

etc
