PHP、Java和Go语言在大数据处理能力方面的对比

<?php
$file = fopen("bigdata.txt", "r");
while(!feof($file)) {
    $line = fgets($file);
    // 处理一行大数据
}
fclose($file);
?>

import java.io.FileReader;
import java.io.IOException;

            String line;
            while ((line = reader.readLine()) != null) {
                // 处理一行大数据
            }
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
