Publishing essays or papers as a student

Any students published an essay or paper? How did you do it, and what was it on. I’m writing a philosophy paper and would love to publish ( only as it’s useful for uni ).

I published scientific literature as a PhD “student” , you can either submit an abstract to a journal and they will then review & invite you to submit a draft if they deem it suitable or some places will invite people to write a paper although this is typically more likely with a “special issue” following an academic conference but not exclusively. Or you can do a chapter in a book (or full book), typically a lead editor or publisher will approach people they want with details.
Prior to having a PhD or suitable credentials highlighting your background as relevant & experienced you won’t get published in a professional academic context (for obvious reasons). Even PhD candidates typically have reputable professors names alongside their name on submissions. Although there is nothing stopping you uploading your work open-source somewhere and then promoting it.
