How can the PHP script be optimized to efficiently handle bulk address imports and automate the process seamlessly?

To optimize the PHP script for handling bulk address imports efficiently and automating the process seamlessly, we can utilize batch processing techniques and optimize database interactions. By breaking down the import process into smaller batches, we can prevent memory issues and improve performance. Additionally, implementing error handling and logging mechanisms can help in identifying and resolving any issues that may arise during the import process.

// Sample PHP code snippet for optimizing bulk address imports

// Define the batch size for processing
$batchSize = 100;

// Read the addresses from a CSV file or any other data source
$addresses = []; // Populate this array with addresses from the data source

// Chunk the addresses array into batches
$addressBatches = array_chunk($addresses, $batchSize);

// Process each batch of addresses
foreach ($addressBatches as $batch) {
    // Insert or update addresses in the database
    foreach ($batch as $address) {
        // Perform database operations for each address
    }
    
    // Log the successful batch processing
    // Add error handling for any failed batches
}
