Lets learn
1.Create file as imageuploading.php and implement code in it for uploading multiple images using POST method.
<form> and add enctype='multiple/form-data' attribute.
<form action="upload.php" method="POST" enctype="multipart/form-data">
type='file' element and for enabling multiple files selection add multiple attribute. For reading all selected files when <form> submitted add [] brackets at the end of a name which denotes an Array.
<input type="file" name="file[]" id="file" multiple>
Complete Code to post multiple images in html:
<!DOCTYPE html>
<html lang="en">

3.Explanation of Code.
if any user uploaded a file using this field, we can obtains its details like the name, type, size, temporary name or any error occurred while attempting the upload via the $_FILES["files"] associative array, like this:
$_FILES["files"]["name"] — This array value specifies the original name of the file, including the file extension. It doesn't include the file path.
$_FILES["files"]["type"] — This array value specifies the MIME type of the file.
$_FILES["files"]["size"] — This array value specifies the file size, in bytes.
$_FILES["files"]["tmp_name"] — This array value specifies the temporary name including full path that is assigned to the file once it has been uploaded to the server.
$_FILES["files"]["error"] — This array value specifies error or status code associated with the file upload, e.g. it will be 0, if there is no error.
