What are the limitations of using <input type="file"> to retrieve file paths in PHP?

When using <input type="file"> in PHP, you can only retrieve the file name, not the full file path on the client's machine due to security restrictions. To solve this issue, you can use the $_FILES superglobal array in PHP to access the file information, including the temporary file location on the server. 

&lt;?php
if ($_FILES[&#039;file&#039;][&#039;error&#039;] === UPLOAD_ERR_OK) {
    $tempFilePath = $_FILES[&#039;file&#039;][&#039;tmp_name&#039;];
    $newFilePath = &#039;uploads/&#039; . $_FILES[&#039;file&#039;][&#039;name&#039;];
    
    if (move_uploaded_file($tempFilePath, $newFilePath)) {
        echo &#039;File uploaded successfully.&#039;;
    } else {
        echo &#039;Error uploading file.&#039;;
    }
} else {
    echo &#039;File upload error: &#039; . $_FILES[&#039;file&#039;][&#039;error&#039;];
}
