Hi Im dealing with UK postcodes

 

I need to check the first to chars in a $string against vars contained in an array.

 

ie

 

$postcode= "M23 4EF"

 

$Array_to Check = ('SW','NW','SF')

 

Not sure what is the best way to do this...

 

Just need to check if 1st chars in $postcode contain any of $Array_to_check and return tru/false/

 

Thanks

<?php

function makeRegEX(&$item, $key)
{
$item = '/^' . $item . '/';
}

$postcode= "M23 4EF"

$arr = ('SW','NW','SF');

array_walk($arr, 'makeRegEx');

if (preg_match($arr,$postcode))
{
echo "Found";
}
