move_uploaded_file()

What is the move_uploaded_file() Function?

The move_uploaded_file() function is a built-in PHP function that moves an uploaded file to a new location. Note: This function only works with files that were uploaded via HTTP POST. This function takes two parameters: the temporary name of the file and the destination path.

Here's the basic syntax of the move_uploaded_file() function:

The PHP syntax of move_uploaded_file()

move_uploaded_file(<temp_filename>, <destination_path>);

Where <temp_filename> is the temporary name of the uploaded file, and <destination_path> is the path to the new location.

How to Use the move_uploaded_file() Function?

Using the move_uploaded_file() function is straightforward. Here are the steps to follow:

1. Verify the file upload succeeded by checking $_FILES['file']['error'].
2. Specify the destination path for the file.
3. Call the move_uploaded_file() function, passing in the temporary filename and the destination path.

Here's an example code snippet that demonstrates how to use the move_uploaded_file() function:

How to Use the move_uploaded_file() Function?

<?php

if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $uploaded_file = $_FILES['file']['tmp_name'];
    $destination_path = '/path/to/new/location/' . basename($_FILES['file']['name']);
    if (move_uploaded_file($uploaded_file, $destination_path)) {
        echo "File uploaded successfully!";
    } else {
        echo "Error uploading file.";
    }
} else {
    echo "File upload failed.";
}

In this example, we first verify that the upload succeeded using $_FILES['file']['error']. We then specify the destination path for the file and use basename() to safely extract the filename and prevent path traversal vulnerabilities. Finally, we use the move_uploaded_file() function to move the uploaded file to the new location. If the file is moved successfully, we print out a success message. If there is an error moving the file, we print out an error message.
