Question

Assume I have a array like this:

$arr1 = ('red', 'blue');

and then I do:

list($color1, $color2, $color3) = $arr1;

I get 2 nice variables with the array values.

Is it possible to somehow set $color3 to have a default value in case it’s not present in the array, but with as little code as possible (without using if checks and stuff like that)?

I tried with list($color1 = 'default', $color2 = 'default', $color3 = 'default') = $arr1; but it doesn’t work…

Answer 1

$yourColors = array('red', 'green');
$defaultColors = array('yellow', 'blue', 'cyan');

list($color1, $color2, $color3) = $yourColors + $defaultColors;

$color1 will be ‘red‘

$color2 will be ‘green‘

$color3 will be ‘cyan‘
