PHP: Convert city, state, country to appropriate header

I have a city, state, countries such as:

NEW YORK, NY, US
REDMOND, WA, US
US
HONG KONG
CALGARY, CA
E. SYRACUSE, NY, US

I would like to convert them to their proper cause (New York, New York, USA, etc.). What's a quick way to do this in PHP?

function title_case($val) {
    return mb_convert_case($val[0], MB_CASE_TITLE, "UTF-8");
}

$locs = array(
  'NEW YORK, NY, US',
  'REDMOND, WA, US',
  'US',
  'HONG KONG',
  'CALGARY, CA',
  'E. SYRACUSE, NY, US',
);
foreach ($locs as &$loc) {
  $loc = preg_replace_callback( '/\b\w{3,}\b/', "title_case", $loc);
}
print_r($locs);

// Array
// (
//     [0] => New York, NY, US
//     [1] => Redmond, WA, US
//     [2] => US
//     [3] => Hong Kong
//     [4] => Calgary, CA
//     [5] => E. Syracuse, NY, US
// )

What do you mean by doing the right thing? I have a feeling that I am missing something as far as you need it, so it would be nice if you could figure out exactly what this data is and how you want to handle it.

You can use ucfirst

to make the first letter of each word uppercase, and you can use explode

to split the string into appropriate segments:

$str = "NEW YORK, NY, US";
list($city, $state, $country) = explode(',', $str);
$city = ucfirst(strtolower($city));

In the examples you have provided, you will not need to do anything to specify the country and country, although there is strtoupper

if you want them to be capitalized.

However, this is a tricky proposition as I am sure there are situations in which whatever conclusion it gives might not be the "correct" way to write a specific city, although I cannot think of any examples from the top of I sure there are some.

I also notice that there are a few strings that only have a country ("USA"), and some that only have a city ("HONG KONG"), there is no reliable way to determine what the string contains. You can try matching it against a list of countries and cities, etc., but it looks like whatever solution you come up with will be a guessing game at best.

There will always be some edge cases without a dictionary, so I think this approach would be the best

vinko@parrot:~$ cat cap.php
<?php

$list = "NEW YORK, NY, US
REDMOND, WA, US
US
HONG KONG
CALGARY, CA
E. SYRACUSE, NY, US";

$countries = array("HONG KONG", "US", "CA");
$states = array("NY","WA");

$list = split("\n",$list);

$out = "";
foreach ($list as $line) {
        list($first,$second,$third) = split(",",$line);

        //Here you check in a dictionary for country/state to
        //like this:

        if (!in_array($first,$countries) && !in_array($first,$states)) {
                $first = ucwords(strtolower($first));
        }
        if ($third) { $out.= $first.",".$second.",".$third; }
        else if ($second && !$third) { $out.= $first.",".$second; }
        else { $out.= $first; }
        $out.= "\n";
}
echo $out;
?>
