What are the best practices for handling and processing data from a text file in PHP?

When handling and processing data from a text file in PHP, it is important to follow best practices to ensure efficient and secure operations. One common approach is to read the contents of the text file line by line, process each line as needed, and then close the file handle when finished to free up system resources. 

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

// Process each line of the file
while (!feof($file)) {
    $line = fgets($file);
    // Perform data processing operations on $line
}

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