What are the potential pitfalls of checking for duplicate entries within a certain timeframe in PHP?

One potential pitfall of checking for duplicate entries within a certain timeframe in PHP is that it may not be efficient if the dataset is large. To solve this issue, you can utilize database queries to check for duplicates directly at the database level, which is more efficient than iterating through a large dataset in PHP. 

// Assuming you have a database connection established

// Query to check for duplicate entries within a certain timeframe
$query = "SELECT COUNT(*) FROM your_table WHERE your_condition_here";

// Execute the query
$result = mysqli_query($connection, $query);

// Fetch the result
$count = mysqli_fetch_array($result)[0];

// Check if there are duplicate entries
if ($count > 0) {
    echo "Duplicate entries found within the specified timeframe.";
} else {
    echo "No duplicate entries found within the specified timeframe.";
}
