Generate a class attribute from an array of classes and sanitises the classes
<?php
// Example.
$myclasses = [ 'my-class', 'some-other-class', '<script>console.log(hi);</script>' ];
printf(
'<div %1$s>%2$s</div>',
cameronjonesweb_generate_class_attribute( $myclasses ),
'My content'
);
// Displays: ?>
<div class="my-class some-other-class scriptconsoleloghiscript">My content</div>
<?php
/**
* Generates a class attribute for a HTML element and sanitises the classes
* We can't just run `sanitize_html_class` on imploded classes as the spaces will be stripped out
* So we have to loop through each class and sanitise each class individually
*
* @param array $classes The classes to add to the element.
* return string The generated class attribute, or an empty string if the array is empty
