Are there any potential pitfalls to be aware of when working with large amounts of data like 40,000 text lines in a database using PHP?

One potential pitfall when working with large amounts of data like 40,000 text lines in a database using PHP is the risk of memory exhaustion due to loading all the data into memory at once. To address this issue, you can fetch the data in smaller chunks or use pagination to limit the amount of data loaded into memory at any given time. 

// Fetch data in smaller chunks
$limit = 1000; // Number of records to fetch at a time
$offset = 0; // Initial offset
do {
    $query = "SELECT * FROM table LIMIT $offset, $limit";
    $result = mysqli_query($connection, $query);
    
    // Process the fetched data
    
    $offset += $limit;
} while(mysqli_num_rows($result) > 0);
