Function of $_FILES in File Add
In truth, PHP provides a superglobal variable $_FILES that we use to retrieve the properties of a file. After we add a file on the server, we want some properties of the file to verify earlier than importing. Accordingly, the $_FILES superglobal variable, which is principally an associative array has the next fields:
$FILES[‘name’] It represents the file identify. That is the precise identify of the file that we’re importing.
$FILES[‘temp_name’] Earlier than the file is uploaded to the server, it will get a short lived deal with. Due to this fact, ‘tmp_name’ represents the identify of that non permanent deal with.
$_FILES[‘type’] The kind represents the file extension. Therefore, we will use this subject to limit the importing of the file to particular extensions.
$_FILES[‘size’] Principally, it’s the measurement of the file in bytes.
$_FILES[‘error’] In truth, a file could encounter sure errors throughout add. So, this subject represents the errors encountered throughout add.
