Assign string based on integer [duplicate]

Question

I have a list of values eg. 1 - 100, what I need to do is the following: There are values relating to these number, so 1 = pink, 2 = blue, 3 = grey, etc. when it gets to 12 = green, it has to start over, so then 13 would be pink again, and the whole sequence is restarted.

Any assistance will be greatly appreciated. All coding done in PHP.

Just use the modulo and a array of colors.

<?php

$number = 13;
$colors = ['pink',   'blue',   'grey',
           'yellow', 'red',    'green',
           'white',  'black',  'purple',
           'brown',  'orange', 'ocean'];

// number-1 if you want the pink color
echo $colors[($number-1) % count($colors)];

Clean and elegant solution. I would replace 12 with count($colors)

@tkovs: it's cleaner than my switch if we need just one action. +1

@cbaconnier yeah, count($colors) is more readable, ty.

Simple task for modulo operator and switch.

<?php

$number = 98;

switch ($number % 12) {
    case 1:
        $color: pink;
        break;

    case 2:
        $color: blue;
        break;

    ...
}

echo $color;

?>
