How can PHP developers handle large datasets, such as a table with 110 columns and 30,000 rows, effectively in terms of memory usage and performance?

Handling large datasets like a table with 110 columns and 30,000 rows can be challenging in terms of memory usage and performance. One effective way to handle this is to retrieve data from the database in chunks rather than loading the entire dataset into memory at once. This can be achieved by using pagination or limiting the number of rows fetched at a time. 

// Example code snippet for fetching data in chunks
$limit = 1000; // Number of rows to fetch at a time
$totalRows = 30000; // Total number of rows in the table

for ($offset = 0; $offset < $totalRows; $offset += $limit) {
    $query = "SELECT * FROM table_name LIMIT $offset, $limit";
    // Execute the query and process the results
}
