What are the steps involved in uploading a file from a client's machine to a server in PHP?

To upload a file from a client's machine to a server in PHP, you need to create a form with an input field of type "file" and set the form's enctype attribute to "multipart/form-data". Then, in the PHP script that processes the form submission, you can use the $_FILES superglobal to access the uploaded file and move it to the desired location on the server. 

<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload File">
</form>
```

```php
<?php
if(isset($_FILES['file'])){
    $file = $_FILES['file'];
    $file_name = $file['name'];
    $file_tmp = $file['tmp_name'];
    move_uploaded_file($file_tmp, "uploads/".$file_name);
    echo "File uploaded successfully!";
}
?>
