Country Package for Laravel

It is often or not we need a country listing in our package to display in the view or dropdown HTML component. Instead of creating table of coutries we could use a proven PHP package library to do that.

I come across this library league/iso3166 and have use it ever since.

Methods you can use are:

   #to define the library 
   use League\ISO3166\ISO3166;

   #to get all countries
   $countries = (new ISO3166())->all();

   #to get a specific country details and currency for Philippines
   $country => (new ISO3166())->alpha3('PHL');

   #to get a specific country name for Philippines
   $country_name' => ((new ISO3166())->alpha3('PHL'))['name'];

PHP Number to Romans Numeral conversion

Just Playing with PHP lately and thought of a Digit to Roman Numerals conversion. This is one of my testing exam before and just recall how I did it.

$romanString = '';
$value = 975;
 do {
   $converted = convertToRoman($value); 
   $value = $converted[0];
   $romanString = $romanString .  $converted[1];
 } while ( $value != 0);

echo $romanString;

 function convertToRoman($number){
    $returnValue = 0;
    $returnString = '';
 $romanArray = [[1000,'M'],[900,'CM'],[100,'C'],[90,'XC'],[50,'L'],[10,'X'],[9,'IX'],[5,'V'],[4,'IV'],[1,'I']];

 foreach ($romanArray as  $value) {
  
       if ($number >= $value[0]) {
            $returnValue = $number - $value[0];
            $returnString = $value[1]; 
            break;
       }        

 }
     
 return array($returnValue,$returnString);
}

Laravel Filtering Eloquent Results and Left Join Example

These scripts join table demographics to countries table by looking into line 2.
Line 7 to 18 shows how can we filter the resulted collection on the results.
Finally, this returns an array of demographics with age, gender, and location as indexes.

       $mixDemographics =DB::table('demographics')
            ->leftJoin('countries', 'demographics.country_id', '=', 'countries.iso_3166_2')
            ->where('user_id',$userId)
            ->get();

        $demographics = [];
        $demographics['age'] = $mixDemographics->filter(function ($demo) {
            return ($demo->metric == 'AGE');
        });

        $demographics['gender'] = $mixDemographics->filter(function ($demo) {
            return ($demo->metric == 'GENDER');
        });


        $demographics['location'] = $mixDemographics->filter(function ($demo) {
            return ($demo->metric == 'COUNTRY');
        });
