It all depends on your background. How many languages do you speak already? How many do you program in?
Are you learning "mainstream" Spanish, or a dialect? PHP for WordPress or PHP for Laravel? PHP 5 or PHP 7?
This morning, I was thinking about sí vs si and how confusing that was when I was first learning Spanish. Before I understood they were two different words, I had to wrap my brain around a different way of thinking when I put a sentence together.
I learned PHP in the 4.x days, and it was so close to writing C or basic Java. It could be embedded in HTML content like a JSP snippet. I just had to learn a little syntax.
Cualquier lenguaje humano es mucho mas complejo que cualquier lenguaje de programación
