note 35058 added to function.ereg

OK. My Take on British Postcodes. I had a sample of nearly 90,000 to check and the following worked best. It handles CR0 0JP and BFPO 10 (British Forces Posted Overseas) which the others posted here didn't. The cleanupPostcode function corrects some common errors prior to validation. function cleanupPostcode ($postcode) { $postcode = strtoupper($postcode); $postcode = ereg_replace('[[:punct:]]', ' ', $postcode); $postcode = ereg_replace('[[:space:]]+', ' ', $postcode); $postcode = str_replace(' O',' 0', $postcode); if ($postcode{0} == '0') $postcode{0} = 'O'; return $postcode; } $postcode = cleanupPostcode($postcode); $valid = eregi('^(([A-Z][A-Z]?)([1-9]*[0-9A-HJ-RT-Y]?))|(BFPO) ?(([0-9]{1}[ABD-HJLNP-UW-Z]{1,2})|([0-9]{2}))$', $postcode); This resulted in "fixing" over 600 carelessly entered postcodes prior to validation. Only safe fixes are performed. ---- Manual Page -- http://www.php.net/manual/en/function.ereg.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35058 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35058&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35058&report=yes
