PHP 버전 자바 스크립트 함수 (우편 번호 확인)

Question

내가 PHP에서이를 달성 할 수있는 방법을 찾고 있어요 ... ,이 웹 사이트 지침에 따라 http://www.braemoor.co.uk/software/postcodes.shtml하지만 거기에 자바 스크립트 메서드의 데모를 필요로하는 PHP 함수를 호출하는 방법에 대한 지침이 없습니다.

현재 코드는 javascript이며, 최근에야 내 자바 스크립트 기능을 매우 쉽게 우회 할 수 있다는 것을 발견했습니다. 그래서 지금은 같은,하지만 serverside을 달성하기 위해 PHP를 찾고 있습니다.

Version:  V5.0 
Date:   8th November 2012 
       Specific support added for new BFPO postcodes 

Parameters: $postcode - postcode to 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.

Answer 2

$newPostCode = checkPostCode($_POST['Postcode']); 
if ($newPostCode) { 
    // Do stuff with $newPostCode 
} else { 
    echo "Postcode has invalid format"; 
} 

당신은 여전히 ​​checkPostCode() 함수를 작성해야합니다.
