How can PHP developers access and display files uploaded to the temporary directory on the server, and what steps should be taken to troubleshoot missing uploaded files?

To access and display files uploaded to the temporary directory on the server, PHP developers can use the $_FILES superglobal array to retrieve information about the uploaded file, move the file from the temporary directory to a permanent location on the server, and then display the file using appropriate HTML tags or PHP functions. To troubleshoot missing uploaded files, developers should check the file size limits, file permissions, and server configurations to ensure that files are being uploaded successfully. 

<?php
if(isset($_FILES['uploaded_file']) && $_FILES['uploaded_file']['error'] === UPLOAD_ERR_OK) {
    $temp_file = $_FILES['uploaded_file']['tmp_name'];
    $target_file = 'uploads/' . $_FILES['uploaded_file']['name'];
    
    if(move_uploaded_file($temp_file, $target_file)) {
        echo 'File uploaded successfully: <a href="' . $target_file . '">View File</a>';
    } else {
        echo 'Error uploading file. Please try again.';
    }
} else {
    echo 'Error uploading file. Please check file size limits and permissions.';
}
?>
