Question

I have an comma seperated list of values held as a string:

blue, left-right-middle, panther.png

I then have three functions:

1. Sets background colour

2. Sets order of columns for layout

3. Sets a profile image

At the moment I use a for each loop to explode the values into seperate strings, but how can I better control the results.

E.g

First result of array = Sets background colour
    Second result of array = Sets order of columns
    Third results of array = profile image

Can I write the results of the array to 3 seperate variables in anyway, so I can assign the variable to each function?

Like so:

    First result of array = $backgroundColour
    Second result of array = $orderColumns
    Third results of array = $profileImage

Any ideas how I might go about this?

Use list:

$line = 'blue, left-right-middle, panther.png';
list( $bkgColor, $columnOrder, $profileImage ) = explode( ', ', $line );

echo 'Background color: ' . $bkgColor . "<br />\n";
echo 'Column order: ' . $columnOrder. "<br />\n";
echo 'Profile image: ' . $profileImage . "<br />\n";
