Andy,
There are some ready made scripts for dealing with UK post codes on the relevant page
on the PHP site:

Subject: [PHP] Zip to postcode[Scanned]
Can someone please tell me how i change the following code:
if (!ereg(^[0-9]{5,5}(\-[0-9]{4,4})?$,$postcode))
to a UK postcode QQ1 1QQ
When i fill out the form it tells me that the postcode is not valid and i
think it is because it is in zip code format.
Thank you
Andy

re: [PHP] Zip to postcode
sorry, don't have anything to add for code, but just a note to remember that UK post
codes can also be in the form...
QQ11 1QQ
Q1 1QQ
Q11 1QQ
QQ1 1QQ
so it's a real pain to write an expression for this...

Re: [PHP] Zip to postcode
Hi Andy,
The following function seems to work for me:
function split_postcode ($postcode) {
if(eregi('(^[A-Z]{1,2})([0-9|A-Z]{1,2}).*([0-9][A-Z]{2}$)', str_replace('
', '', $postcode), $parts)){
$outcode=strtoupper(sprintf('%s%s%s', $parts[1], @str_repeat(' ',
4-strlen($parts[1])-strlen($parts[2])), $parts[2]));
$incode=strtoupper($parts[3]);
return array($outcode, $incode);
}else{
return False;
}
}

There are some ready made scripts for dealing with UK post
codes on the relevant page on the PHP site:
http://www.php.net/manual/en/function.ereg.php
And not one of them is 100% correct!! This would be my stab:
preg_match('/^([A-Z]{1,2}([0-9]{1,2})|[0-9][A-Z])|GIR)'
. ' ?[0-9][A-Z]{2}$/i', $postcode)
(I've divided the pattern in two here simply to avoid strange line wrapping!)
One of the user notes referred to says that postcodes are sometimes written with a
space after the initial letters; although technically this is incorrect, adjusting to
allow it would give:
preg_match('/^([A-Z]{1,2} ?([0-9]{1,2})|[0-9][A-Z])|GIR)'
. ' ?[0-9][A-Z]{2}$/i', $postcode)
Another states that the set of letters in the last two positions is restricted -- I
can't vouch for the accuracy of this, but if it's the case the match would become:
preg_match('/^([A-Z]{1,2} ?([0-9]{1,2})|[0-9][A-Z])|GIR)'
. ' ?[0-9]}[ABD-HJLNP-UW-Z]{2}$/i', $postcode)
Finally, if you really, really want to accept only completely valid postcodes (not
just validly formatted ones), you should get the full list of postcode area
identifiers (the initial letter or two) and validate against those -- plus any local
peculiarities that occur (for example, in my local postcode area, the final digit is 2
in *all* cases). (Well, I guess here we're getting into the realms of paying for the
Royal Mail's postcode database!!)
Cheers!
Mike
