How can PHP scripts be optimized for efficient data import processes, especially when dealing with large datasets?

To optimize PHP scripts for efficient data import processes, especially with large datasets, it is important to use batch processing and optimize database queries. Batch processing involves breaking the data into smaller chunks to prevent memory overflow, while optimizing queries involves using bulk insert statements and indexing. Additionally, consider using tools like PHP's built-in functions for file handling and database interactions to streamline the import process.

// Example code for batch processing data import
$batchSize = 1000;
$data = []; // Assuming data is fetched from a file or another source

for ($i = 0; $i < count($data); $i += $batchSize) {
    $batchData = array_slice($data, $i, $batchSize);
    
    // Perform database insert using $batchData
    // Example: INSERT INTO table_name (column1, column2) VALUES (value1, value2), (value3, value4), ...
}
