/*==============================================================================
Application: Utiity Function
Author: John Gardner
Version: V1.0
Date: 25th December 2004
Description: Used to check the validity of a UK postcode
Version: V2.0
Date: 8th March 2005
Description: BFPO postcodes implemented.
The rules concerning which alphabetic characters are alllowed in
which part of the postcode were more stringently implementd.
Parameters: $postcode - postcodeto be checked. This is returned reformatted
if valid.
This function checks the value of the parameter for a valid postcode format. The
space between the inward part and the outward part is optional, although is
inserted if not there as it is part of the official postcode.
The functions returns a value of false if the postcode is in an invalid format,
and a value of true if it is in a valid format. If the postcode is valid, the
parameter is loaded up with the postcode in capitals, and a space between the
outward and the inward code to conform to the correct format.
Example call:
if (!checkPostcode($postcode) ) {
echo 'Invalid postcode <br>';
}
------------------------------------------------------------------------------*/
function checkPostcode (&$toCheck) {
// Permitted letters depend upon their position in the postcode.
$alpha1 = "[abcdefghijklmnoprstuwyz]"; // Character 1
$alpha2 = "[abcdefghklmnopqrstuvwxy]"; // Character 2
$alpha3 = "[abcdefghjkstuw]"; // Character 3
$alpha4 = "[abehmnprvwxy]"; // Character 4
$alpha5 = "[abdefghjlnpqrstuwxyz]"; // Character 5
// Expression for postcodes: AN NAA, ANN NAA, AAN NAA, and AANN NAA
$pcexp[0] = '^('.$alpha1.'{1}'.$alpha2.'{0,1}[0-9]{1,2})([0-9]{1}'.$alpha5.'{2})$';
// Expression for postcodes: ANA NAA
$pcexp[1] = '^('.$alpha1.'{1}[0-9]{1}'.$alpha3.'{1})([0-9]{1}'.$alpha5.'{2})$';
// Expression for postcodes: AANA NAA
$pcexp[2] = '^('.$alpha1.'{1}'.$alpha2.'[0-9]{1}'.$alpha4.')([0-9]{1}'.$alpha5.'{2})$';
// Exception for the special postcode GIR 0AA
$pcexp[3] = '^(gir)(0aa)$';

$pcexp[4] = '^(bfpo)([0-9]{1,4})$';
// c/o BFPO numbers
$pcexp[5] = '^(bfpo)(c\/o[0-9]{1,3})$';
// Load up the string to check, converting into lowercase and removing spaces
$postcode = strtolower($toCheck);
$postcode = str_replace (' ', '', $postcode);
// Assume we are not going to find a valid postcode
$valid = false;
// Check the string against the six types of postcodes
foreach ($pcexp as $regexp) {

// Load new postcode back into the form element
$toCheck = strtoupper ($matches[1] . ' ' . $matches [2]);
// Take account of the special BFPO c/o format
