Okay, let’s take a look at the simplest php file upload tutorial. Well, we will use move_uploaded_file to upload local articles to the server.

Using PHP, you can upload files to the server.

-------------------------------------------------- -------------------------------

Create a file upload form
Forms for users to upload files can be very helpful.

Take a look at the HTML form below for file upload:

<html>
<body>

Copy after login

<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" /> 
<br />
<input type="submit" name="submit" value="Submit" />
</form>

Copy after login

</body>
</html>

Copy after login

Please note the following HTML form above:

The enctype attribute

tag specifies the content type used when a form is submitted. "Multi/form-data" is used when a form that requires binary data, such as file content, will be uploaded
The type="file" attribute specifies that the input of the tag should be processed as a file. For example, when viewing in a browser, there will be a Browse button next to the input field
NOTE: Allowing users to upload files is a big security risk. Only allow file uploads to trusted users.

Create upload script
The " upload_file.php " file contains the code to upload files:

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

It’s that simple.
