Working with PHP arrays and mapping them based on textual data

When processing orders, different text strings are returned based on the shipping method selected. Examples of these text strings include:

productmatrix_Pick-up_at_Store
productmatrix_Standard
productmatrix_3-Day_Delivery
productmatrix_Pick-up_at_Store_-_Rush_Processing
productmatrix_2-Day_Delivery
productmatrix_1-Day_Delivery_-_Rush_Processing

In order to map these text strings to production codes, a key-value pair map is used. The key represents the text to match on and the value indicates the corresponding production code. The mapping table looks like this:

$shipToProductionMap = array(
    "1-day" => 'D',
    "2-day" => 'E',
    "3-day" => 'C',
    "standard" => 'Normal',
    "pick-up" => 'P'
);

The objective is to create a function that can return the correct production code from the $shipToProductionMap based on the input string provided. This function could look something like:

function getCorrectShipCode($text){
 if(strtolower($text) == if we find a hit in the map){
   return $valueFromMap;
 }
}

For instance, if the function call is as follows:

$result = getCorrectShipCode('productmatrix_Pick-up_at_Store');
//$result = 'P';

What would be the most efficient approach to achieve this?

Answer №1

To accomplish this task, you can utilize the foreach loop along with the stripos function for matching purposes.

echo getShipCode('productmatrix_2-Day_Delivery');

function getShipCode($text){

    $shipMapping = array(
                  "1-day" => 'D',
                  "2-day" => 'E',
                  "3-day" => 'C',
                  "standard" => 'Normal',
                   "pick-up" => 'P'
    );

    foreach($shipMapping as $key => $value)
    {

        if(stripos($text, $key) !== false) 
        {

            return $value;

            break;
        }
    }

Here is a function called getCorrectShipCode that compares array key values in the ship to production map against a string passed to it using preg_match. This function works by iterating through all values in a test array:

// Populate the test array with strings.
$test_strings = array();
$test_strings[] = 'productmatrix_Pick-up_at_Store';
$test_strings[] = 'productmatrix_Standard';
$test_strings[] = 'productmatrix_3-Day_Delivery';
$test_strings[] = 'productmatrix_Pick-up_at_Store_-_Rush_Processing';
$test_strings[] = 'productmatrix_2-Day_Delivery';
$test_strings[] = 'productmatrix_1-Day_Delivery_-_Rush_Processing';

// Iterate through test array strings.
foreach ($test_strings as $test_string) {
  echo getCorrectShipCode($test_string) . '<br />';
}

// The actual 'getCorrectShipCode()' function.
function getCorrectShipCode($text) {

  // Define the ship to production map.
  $shipToProductionMap = array(
      "1-day" => 'D',
      "2-day" => 'E',
      "3-day" => 'C',
      "standard" => 'Normal',
      "pick-up" => 'P'
  );

  // Set the regex pattern based on the ship to production map keys.
  $regex_pattern = '/(?:' . implode('|', array_keys($shipToProductionMap)) . ')/i';

  // Use regex to match the value based on the ship to production map keys.
  preg_match($regex_pattern, $text, $matches);

  // Set the result if there is a match.
  $ret = null;
  if (array_key_exists(strtolower($matches[0]), $shipToProductionMap)) {
    $ret = $shipToProductionMap[strtolower($matches[0])];
  }
  
  // Return the result.
  return $ret;

} // getCorrectShipCode
