Learning the basics of php "if...elseif...else" is the most valuable PHP function you'll encounter during your WordPress journey! I've used this simple bit of php hundreds of times over the years, sometimes in very basic ways and sometimes in complex ways. +Bonus points for learning the basics of php arrays. Also, a core WordPress feature I code regularly into php is shortcodes. For example, just last week, I had to write a simple shortcode to display the author link in a specific way - I used this shortcode within Beaver Builder. Without this custom shortcode, I would have been stuck!

Quand les fonctions natives Wordpress ne suffisent pas (pour le développement d'un module par exemple), il est possible de créer ses propres fonctions pour répondre à ses besoins à l'intérieur du fichier "functions.php" de son module.
