In what ways can the amount of data being processed impact the performance of a PHP script and lead to error messages?

When a PHP script is processing a large amount of data, it can lead to performance issues such as slow execution times or memory exhaustion, which can ultimately result in error messages. To improve performance, consider optimizing the script by limiting the amount of data being processed at once, using pagination techniques, or implementing caching mechanisms. 

// Example of limiting the amount of data being processed at once
$limit = 100; // Limit the number of records to process at a time

// Query to fetch data with limit
$query = "SELECT * FROM table_name LIMIT $limit";

// Execute the query and process the results
$result = mysqli_query($connection, $query);
while ($row = mysqli_fetch_assoc($result)) {
    // Process each row of data
}
