Скачать или смотреть PHP Uploading images and files .

Welcome to PHP programming,
In PHP, it is possible to upload files such as images, videos and any other files.

Creating an Upload File Form
To allow users to upload files from a form can be very useful.

Let us write a html form for uploading:

Save it in our server i.e., xampp/htdocs.

Notice the following about the html forms above:

1) The enctype attribute of the form tag specifies which content-type to use when submitting the
form.

2) "multipart/form-data" is used when a form requires binary data, like the contents of a file, to
be uploaded.

3) The type="file" attribute of the input tag specifies that the input should be processed as a
file. For example, when viewed in a browser, there will be a browser-button next to the input
field.

Creating the Upload script

By using the global PHP $_FILES array we can upload files from a client computer to the remote
server.

The first parameter is the form's input name and the second index can be either "name", "type",
"size", "tmp_name", "error".

Like the following:

1) $_FILES["file"]["name"] - the name of the uploaded file.
2) $_FILES["file"]["type"] - the type of the uploaded file.
3) $_FILES["file"]["size"] - the size in bytes of the uploaded file.
4) $_FILES["file"]["tmp_name"] - the name of the temporary copy of the file stored on the server.
5) $_FILES["file"]["error"] - the error code resulting from the file upload.

This is a simple way of uploading files.

Saving the Uploaded File

The example above create a temporary copy of the uploaded files in the PHP temp folder on the
server.
The temporary copied file disappears when the script ends. To store the uploaded file we need to
copy it to a difficult location:

move_uploaded_file(sourcepath,destinationpath);

The code in PHP would look like this:



move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]);


The uploaded file is stored in "upload/" . $_FILES["file"]["name"]

Here the upload is the folder name given where we want the file to be stored.

Before writinng the code to upload a file let us create a folder named "upload" in our server
i.e., xampp/htdocs

Let us write a simple PHP code to upload file

Save it in our server i.e., xampp/htdocs

Run the html form code using the url http://localhost/file.php

This is how the files are uploaded to the server using PHP script.
