Instead of having the 2 following if statements:

	if($row['make']); switch($row['make']){
	case 'Mercedes-Benz': $row[make] = 'Mercedes'; break;
	case 'Chevrolet': $row[make] = 'Chevy'; break;
	case 'Oldsmobile': $row[make] = 'Olds'; break;
	case 'Volkswagen': $row[make] = 'VW'; break;
}
if($row['veh4']); switch($row['veh4']){
	case 'Mercedes-Benz': $row[veh4] = 'Mercedes'; break;
	case 'Chevrolet': $row[veh4] = 'Chevy'; break;
	case 'Oldsmobile': $row[veh4] = 'Olds'; break;
	case 'Volkswagen': $row[veh4] = 'VW'; break;
}

is there a way that I can combine them?

Here's a better solution, in my opinion, as it doesn't require you to have two different conversion lists that are identical.

 

<?php

$makeArray = (
    'Mercedes-Benz' => 'Mercedes',
    'Chevrolet' => 'Chevy',
    'Oldsmobile' => 'Olds',
    'Volkswagen' => 'VW');

if  ($row['make'] && isset($makeArray[$row['make']])) { $row['make'] = $makeArray[$row['make']]; }
if  ($row['veh4'] && isset($makeArray[$row['veh4']])) { $row['veh4'] = $makeArray[$row['veh4']]; }

?>

 

YOu could also make a function

<?php

$makeArray = (
    'Mercedes-Benz' => 'Mercedes',
    'Chevrolet' => 'Chevy',
    'Oldsmobile' => 'Olds',
    'Volkswagen' => 'VW');

function getMake($make) {
  if ($make && isset($makeArray[$make])) { $make = $makeArray[$make]; }
  return $make;
}


$row['make'] = getMake($row['make']);
$row['veh4'] = getMake($row['veh4']);

?>

LOL, I guess it would be helpful if I used "array" when creating an array! That was my fault. Now that I see all of your code however, I would definitely suggest taking ALL of your "conversions" and creating arrays of them in the manner I described. Then put all of those arrays into an included conversion file. Then you can simply call a function for every value you need to convert. This will make your code much more manageable and cleaner:

 

 

Here is an example using some of the lists you have:

 

using the function I have provided your conversion arrays do not need to include converting a value to itself (e.g. 'DD'=> 'DD'). The function will first determine if the value exists as a key in the array, if so it returns the corresponding value. Ff that fails and the value is null it will return the $null value passed to the function if one was given. If neither of those two scenarios is true then the original value is returned.

conversions.php

<?php

$makeArray = array (
    'Mercedes-Benz' => 'Mercedes',
    'Chevrolet' => 'Chevy',
    'Oldsmobile' => 'Olds',
    'Volkswagen' => 'VW');

$salesmanArray = array (
    'Brad'=> 'BG',
    'BG'=> 'BG', //Not needed
    'Doug'=> 'DD',
    'DD'=> 'DD', //Not needed
    'Charles'=> 'CG',
    'CG'=> 'CG', //Not needed
    'Christine'=> 'CC',
    'CC'=> 'CC', //Not needed
    'Jennifer'=> 'JL',
    'JL'=> 'JL', //Not needed
    'Jerry'=> 'JF',
    'JF'=> 'JF', //Not needed
    'Joe'=> 'JC',
    'JC'=> 'JC', //Not needed
    'Dan'=> 'DF',
    'DF'=> 'DF', //Not needed
    'Auction'=> 'Auction'); //Not needed

$dealtypeArray = array (
    'AL'=> 'AL', //Not needed
    'Citi'=> 'Citi', //Not needed
    'UCF'=> 'UCF', //Not needed
    'CF'=> 'CF', //Not needed
    'Cash'=> '$$',
    'IH'=> 'IH', //Not needed
    'Other'=> 'Other'); //Not needed

?>

 

Test page

<?php

include ("conversions.php");

//Set some values for testing
$row['make'] = "Chevrolet";
$row['veh4'] = "Volkswagen";
$row['dealtype'] = "Cash";
$row['salesman'] = "";
$NOF = "N/A";


function abbreviate($value, $array, $null='') {
  if (isset($array[$value])) {
    $value = $array[$value];
  } else if ($value=='') {
    $value = $null;
  }
  return $value;
}

echo "Make: " . abbreviate($row['make'], $makeArray) . "<br>";
echo "Veh4: " . abbreviate($row['veh4'], $makeArray) . "<br>";
echo "Deal Type: " . abbreviate($row['dealtype'], $dealtypeArray, $NOF) . "<br>";
echo "Salesman: " . abbreviate($row['salesman'], $salesmanArray, $NOF) . "<br>";

// Output:
// Make: Chevy
// Veh4: VW
// Deal Type: $$
// Salesman: N/A

?>

 

Also, instead of doing something like this:

 

$row['make'] = abbreviate($row['make'], $makeArray);

 

and using that variable when creating your HTML, I would suggest just using that function when creating your HTML. Like this:

 

$page_body .= "The make you have chosen is " . abbreviate($row['make'], $makeArray);

 

Hope this helps you.

One other suggestion would be to make the keys in the arrays all upper case (or lower case).

 

Then you can change the function to this:

 

  if (isset($array[strtoupper($value)])) {

 

That will add a little more flexibility to the function so "Chevrolet" and "chevrolet" result in the same output: "Chevy"
