Function ConvertExpiryDateToYYMMDD

The following is based on the code I wrote for version 1.5...
  
function ConvertExpiryDateToYYMMDD($theDate) {

  // prepare to convert expiry date to yymmdd format
  // handle dd/mm/yy dates including single digits for dd, mm, yy
  // - e.g. 06/06/03, 6/6/03, 06/6/03, 6/06/03, 06/06/3 etc.
  $position_of_first_slash = strpos($theDate, "/");
  $expiry_day = substr($theDate, 0, $position_of_first_slash);
  $expiry_mm_yy = substr($theDate, $position_of_first_slash + 1, 
                                                strlen($theDate));
  $position_of_second_slash = strpos($expiry_mm_yy, "/");
  $expiry_month = substr($expiry_mm_yy, 0, $position_of_second_slash);
  $expiry_year = substr($expiry_mm_yy, $position_of_second_slash + 1, 
                                                strlen($theDate));
  // if any of dd, mm or yy are single digits then add a leading zero
  if ( strlen($expiry_day) == 1 ) { 
    $expiry_day = "0".$expiry_day; 
  }
  if ( strlen($expiry_month) == 1 ) {
    $expiry_month = "0".$expiry_month; 
  }
  if ( strlen($expiry_year) == 1 ) {
    $expiry_year = "0".$expiry_year; 
  }
  // now able to convert expiry date to yymmdd format
  $expiry_yymmdd = $expiry_year.$expiry_month.$expiry_day;

  return($expiry_yymmdd);

}

 
Here's a program to demonstate that it works for a single given "random" date...
  
<?php

function ConvertExpiryDateToYYMMDD($theDate) {

  // prepare to convert expiry date to yymmdd format
  // handle dd/mm/yy dates including single digits for dd, mm, yy
  // - e.g. 06/06/03, 6/6/03, 06/6/03, 6/06/03, 06/06/3 etc.
  $position_of_first_slash = strpos($theDate, "/");
  $expiry_day = substr($theDate, 0, $position_of_first_slash);
  $expiry_mm_yy = substr($theDate, $position_of_first_slash + 1, 
                                                strlen($theDate));
  $position_of_second_slash = strpos($expiry_mm_yy, "/");
  $expiry_month = substr($expiry_mm_yy, 0, $position_of_second_slash);
  $expiry_year = substr($expiry_mm_yy, $position_of_second_slash + 1, 
                                                strlen($theDate));
  // if any of dd, mm or yy are single digits then add a leading zero
  if ( strlen($expiry_day) == 1 ) { 
    $expiry_day = "0".$expiry_day; 
  }
  if ( strlen($expiry_month) == 1 ) {
    $expiry_month = "0".$expiry_month; 
  }
  if ( strlen($expiry_year) == 1 ) {
    $expiry_year = "0".$expiry_year; 
  }
  // now able to convert expiry date to yymmdd format
  $expiry_yymmdd = $expiry_year.$expiry_month.$expiry_day;

  return($expiry_yymmdd);

}


/*

echo (ConvertExpiryDateToYYMMDD("30/1/05"));
