What are some best practices for handling lazy loading of data from a file in PHP, especially when dealing with large PDF documents?

Lazy loading of data from a file in PHP, especially when dealing with large PDF documents, involves reading and processing the file in chunks to avoid loading the entire file into memory at once. This helps improve performance and reduce memory usage when working with large files. 

// Open the PDF file for reading
$filename = 'large_file.pdf';
$handle = fopen($filename, 'rb');

// Read and process the file in chunks
while (!feof($handle)) {
    $chunk = fread($handle, 1024); // Read 1KB at a time
    // Process the chunk of data here
}

// Close the file handle
fclose($handle);
