What are some best practices for handling large database files in PHP to prevent SQL splitter crashes?

When handling large database files in PHP, it's important to prevent SQL splitter crashes by breaking down the SQL queries into smaller chunks. One way to achieve this is by limiting the number of records fetched in each query and processing them in batches. This approach helps prevent memory overload and improves the efficiency of data retrieval. 

// Set the limit of records to fetch in each query
$limit = 1000;

// Get the total number of records in the database
$totalRecords = $pdo->query("SELECT COUNT(*) FROM your_table")->fetchColumn();

// Loop through the records in batches
for ($offset = 0; $offset < $totalRecords; $offset += $limit) {
    $query = "SELECT * FROM your_table LIMIT $limit OFFSET $offset";
    $stmt = $pdo->query($query);
    
    // Process the fetched records
    while ($row = $stmt->fetch()) {
        // Process each record here
    }
}
