Create Array from String with explode()

By using the PHP explode() function you can easily convert any string to an array, provided there’s a delimiter. What’s a delimiter? It’s just the part of the string used to break it up, like a comma for example.

// Create initial string of CSS classes
$css_classes = "btn, btn--large, btn--wide";

// Convert string to array
$css_classes = explode(', ', $css_classes);

// Example
<a class="<?php echo $css_classes; ?>" href="#">Button!</a>

// Output
<a class="btn btn--large btn--wide" href="#">Button!</a>
