<?php
//echo date_dropdown();
function date_dropdown($year_limit = 0){
        $html_output = '    <div id="date_select" >'."\
";
        $html_output .= '        <label for="date_day">Select date/label>'."\
";

        /*days*/
        $html_output .= '           <select name="date_day" id="day_select">'."\
";
            for ($day = 1; $day <= 31; $day++) {
                $html_output .= '               <option>' . $day . '</option>'."\

            }

        /*months*/
        $html_output .= '           <select name="date_month" id="month_select" >'."\
";
        $months = array("", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
            for ($month = 1; $month <= 12; $month++) {
                $html_output .= '               <option value="' . $month . '">' . $months[$month] . '</option>'."\
";
            }
        $html_output .= '           </select>'."\

        /*years*/
        $html_output .= '           <select name="date_year" id="year_select">'."\

            for ($year = 2001; $year <= 2012; $year++) {
                $html_output .= '               <option>' . $year . '</option>'."\

            }
        $html_output .= '           </select>'."\

        $html_output .= '   </div>'."\

 return $html_output;
}
$text=date_dropdown();

echo $text;

Normally you would do this when the form is submitted.

E.g.

<form action="myScript.php" method="post">
  <label for="date_day">Select date</label>
  <select name="date_day" id="day_select">...</select>
  <select name="date_month" id="day_month">...</select>
  <select name="date_year" id="day_year">...</select>
  <input type="submit" value="Submit" />
</form>

This submits to:

myScript.php

<?php
  $date = $_POST['date_day'] . "-" . $_POST['date_month'] . "-" . $_POST['date_year'];
  $f = fopen("date.txt", "w");
  fwrite($f,$date);
  fclose($f);
?>

However, a text file might not be the best method of storing this information.
Did you think about using a database instead?

Thank you for your reply, as I want leading zeros I made a small addition to your code.


  echo $date = $_POST['date_day'] . "-" . $_POST['date_month'] . "-" . $_POST['date_year'];
  $newDate = date("Y-m-d", strtotime($date));
  $f = fopen("date.txt", "w");
  fwrite($f,$newDate );
  fclose($f);
