本文实例为大家分享了PHP实现统计代码行数小工具，供大家参考，具体内容如下

为了方面统计编程代码行数，做了一个小工具。

自动统计指定目录以及目录下的所有文件。

1. <?php
2. class TotalCode {
3. /**
4. * 统计当前文件有多少行代码，
5. * @return TotalCodeInfo
6. */
7. public function totalByFile($fullFileName) {
8. $fileContent = file_get_contents($fullFileName);
9. $lines = explode("\n", $fileContent);
10. $lineCount = count($lines);
11. for($i = $lineCount -1; $i > 0; $i -= 1) {
12. $line = $lines[$i];
13. if ($line != "") break;
14. $lineCount -= 1; //最后几行是空行的要去掉。
15. }
16. unset($fileContent);
17. unset($lines);
18. $totalCodeInfo = new TotalCodeInfo();
19. $totalCodeInfo->setFileCount(1);
20. $totalCodeInfo->setLineCount($lineCount);
21. return $totalCodeInfo;
22. }
23. /**
24. * 统计当前目录下（含子目录）
25. * 有多少文件，以及多少行代码
26. *
27. * totalInfo = array( "fileCount"=>?, "lineCount"=>? );
28. *
29. * @return TotalCodeInfo
30. */
