What are some best practices for managing large text files in PHP to avoid potential data loss or corruption?

When working with large text files in PHP, it's important to handle them carefully to avoid potential data loss or corruption. One best practice is to read and write the files in chunks rather than loading the entire file into memory at once. This can help prevent memory issues and improve performance when working with large files. 

// Open the large text file for reading
$handle = fopen('large_file.txt', 'r');

// Read and process the file in chunks
while (!feof($handle)) {
    $chunk = fread($handle, 8192); // Read 8KB at a time
    // Process the chunk as needed
}

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