PHP – How to load a FILE in PHP from a form

To find out how to load a file in PHP from a form you have to start by formatting the form correctly. It is mandatory to use the post method as well as the multipart/form-data enctype. otherwise PHP will not receive the necessary data.

In PHP, to recover data, you have to use $_FILES.

print_r ($_FILES);

by doing this, we get different information

Array ( 
    [namefile]Array ( 
       [name]myfile.xml 
       [type]text/xml 
       [tmp_name]/tmp/phpCGlZPa 
       [error]'0' 
       [size]577059 ) )

From this moment on you can do all the necessary actions, such as saving the file on the server or parsing it like an xml.
