逐行修改容量较大的文件的操作 fgets 和fgetcsv

set_time_limit(0);$file = fopen("wordlist.raw","r");while(! feof($file)){$string = fgets($file);//从文件指针中读取一行$array=explode(' ',$string);$array[2] = '"'.$array[2].'"'; $string = implode(' ',$array);file_put_contents("new.raw",$string,FILE_APPEND);}fclose($file);

set_time_limit(0);$file = fopen("wordlist.raw","r");while(! feof($file)){$string = fgetcsv($file);//从文件指针中读取一行并解析CSV字段，返回的结果为数组$array[2] = '"'.$array[2].'"'; $string = implode(' ',$array);file_put_contents("new.raw",$string,FILE_APPEND);}fclose($file);
