按行读取文件的代码(php、c实现)

2. /**
3. * 按行读取文件
4. * @param string $filename
5. * @site bbs.it-home.org
6. */
7. function readFileByLine ($filename)
8. {
9. $fh = fopen($filename, 'r');
11. while (! feof($fh)) {
12. $line = fgets($fh);
13. echo $line;
14. }
16. fclose($fh);
17. }
19. // test
21. $filename = "/home/wzy/test/sort.txt";
23. readFileByLine($filename);

2，c语言按行读取文件

2. #include
3. #include
4. #include
6. #define LEN 1024
8. int main(void)
9. {
10. char filename[LEN], buf[LEN];
11. FILE *fp;
12. int len;
14. scanf("%s", filename);
16. fp = fopen(filename, "r");
18. if (fp == NULL) exit(-1);
20. while (fgets(buf, LEN, fp) != NULL) {
21. len = strlen(buf);
22. buf[len - 1] = '\0'; // 去掉换行符
24. printf("%s\n", buf);
25. }
27. return 0;
28. }
