What are some common pitfalls when trying to display sensor data from a specific URL on a webpage using PHP?

One common pitfall when displaying sensor data from a specific URL on a webpage using PHP is not properly handling errors or exceptions that may occur during the data retrieval process. To solve this issue, it is important to include error handling mechanisms in your PHP code to gracefully handle any potential errors that may arise. 

<?php
$url = "http://example.com/sensor_data";
$data = file_get_contents($url);

if($data === false){
    echo "Error fetching sensor data";
} else {
    // Process and display sensor data here
}
?>
