What potential pitfalls should be considered when implementing a ticker system in PHP?

One potential pitfall when implementing a ticker system in PHP is the risk of high server load due to frequent database queries for updating the ticker. To mitigate this issue, you can implement a caching mechanism to store the ticker data and only update it at specified intervals. 

// Example of implementing a caching mechanism for a ticker system
$cache_time = 60; // Cache data for 60 seconds
$cache_file = 'ticker_cache.txt';

if(file_exists($cache_file) && time() - filemtime($cache_file) < $cache_time) {
    // Load ticker data from cache file
    $ticker_data = file_get_contents($cache_file);
} else {
    // Fetch ticker data from database
    // Update $ticker_data variable with fetched data

    // Save ticker data to cache file
    file_put_contents($cache_file, $ticker_data);
}

// Display ticker data on the webpage
echo $ticker_data;
