Upload CSV to database using php

I’m working on a small project of mine, and I came to the conclusion that the ability to automatically load an excel sheet into my database will be very, very useful, the problem is that I don’t know where I first researched a bit and decided to use a CSV file, created from excel sheet to load data into the table of my database.

Most of the examples I came across look like a mess with the PHP code in html, instead of sharing the logic in different files, like what I have done over the past 2 months.

Now I have a upload form in html:

       <form enctype="multipart/form-data" method="post" id="uploadForm">
          <input name="filesfiles" id="upload" type="file" accept=".csv" class="left" />
          <input type="submit" value="Cargar" />
       </form>

And a small example of how the CSV file looks in the text:

Cedula;Nombre;Apellido1;Apellido2;Correo;IdRol;Estado
1657890;Dominico;Scarlatti;Viera;leetrills@yahoo.com;2;0
5657890;Franz;Listz;Linerman;flizts@hotmail.com;3;0

Or in some other versions of excel:

Cedula,Nombre,Primer Apellido,Segundo Apellido,Correo,IDRol,Estado
126548791,Franz ,Ritter ,von Liszt,fliszt@arppegio.com,3,0
174657109,Sofia ,Asgatovna ,Gubaidulina ,gubaidulina@yahoo.com,3,0

The first row is the name of the columns (which should be ignored when adding information) to the table into which I want to upload the file.
