What are some best practices for reading and processing data from a text file in PHP?

When reading and processing data from a text file in PHP, it is important to follow best practices to ensure efficient and accurate handling of the data. One common approach is to use file handling functions such as fopen, fread, and fclose to open the file, read its contents, and close it properly after processing. Additionally, using functions like fgets or file_get_contents can help in reading the file line by line or as a whole, respectively. 

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

// Read and process each line of the file
while (!feof($file)) {
    $line = fgets($file);
    
    // Process the data from each line
    // Example: echo $line;
}

// Close the file after processing
fclose($file);
