README

Inspired by Laravel Blade's @class directive. What if you could just use that in any PHP? With composer autoloading you can:

<span class="<?= tailwhen([
    'bg-red-800', // always
    'text-white' => is_string('yes'), // condition is true, so style is applied
    'font-bold' => is_numeric('no') // condition is false, so style is not applied
])?>">some text</span>

Results in:

<span class="bg-red-800 text-white">some text</span>

The tailwhen() function takes in an array of classes, optionally with conditionals. Classes without conditions like the bg-red-800 are always outputted. Classes with a condition are only outputted if the condition evaluates to true.

Setup

composer require corrivate/tailwhen

This installs the tailwhen() helper function and sets up autoload for it.
