How can the file handling in the PHP script be improved to reduce memory usage and prevent memory limit errors?

To reduce memory usage and prevent memory limit errors when handling large files in PHP, it is recommended to read and process the file line by line instead of loading the entire file into memory at once. This can be achieved by using functions like `fgets()` or `fgetcsv()` to read the file line by line and process each line individually. 

$file = fopen('large_file.txt', 'r');

while ($line = fgets($file)) {
    // Process each line of the file here
}

fclose($file);
