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。

<?PHP

class TotalCode {

 /**
 * 统计当前文件有多少行代码，
 * @return TotalCodeInfo
 */
 public function totalByFile($fullFileName) {
 $fileContent = file_get_contents($fullFileName);
 $lines = explode("\n",$fileContent);
 $lineCount = count($lines);

 for($i = $lineCount -1; $i > 0; $i -= 1) {
  $line = $lines[$i];
  if ($line != "") break;
  $lineCount -= 1; //最后几行是空行的要去掉。
 }
 unset($fileContent);
 unset($lines);

 $totalCodeInfo = new TotalCodeInfo();
 $totalCodeInfo->setFileCount(1);
 $totalCodeInfo->setLineCount($lineCount);
 return $totalCodeInfo;
 }

 /**
 * 统计当前目录下（含子目录）
 * 有多少文件，以及多少行代码
 *
 * totalInfo = array( "fileCount"=>?,"lineCount"=>? );
 *
 * @return TotalCodeInfo
 */
 public function totalByDir($dirName) {
 $fileList = scandir($dirName);
 $totalCodeDir = new TotalCodeInfo();
 foreach ($fileList as $fileName) {
  if ($fileName == "." || $fileName == "..") continue;
  $fullFileName = $dirName . "/" . $fileName;
  if (is_file($fullFileName)) {
  $totalCodeSub = $this->totalByFile($dirName . "/" . $fileName);
  } else if (is_dir($fullFileName)) {
  $totalCodeSub = $this->totalByDir($dirName . "/" . $fileName);
  } else {
  $totalCodeSub = new TotalCodeInfo();
  }

  $totalCodeDir->increaseByOther($totalCodeSub);
 }
 return $totalCodeDir;
 }

 public function totalByDirOrFile($dirOrFileName) {
 if (is_dir($dirOrFileName)) {
  return $this->totalByDir($dirOrFileName);
 } else if (is_file($dirOrFileName)) {
  return $this->totalByFile($dirOrFileName);
 } else {
  return new TotalCodeInfo();
 }
 }

 public function test() {
 $re = $this->totalByDir("/export/www/pm_web/configs");
 var_dump($re);
 }

 public function main($dirList) {
 $totalCodeAll = new TotalCodeInfo();
 foreach($dirList as $dirName) {
  $totalCodeSub = $this->totalByDirOrFile($dirName);
  $totalCodeAll->increaseByOther($totalCodeSub);
 }
 print_r($totalCodeAll);
 }

}

class TotalCodeInfo {
 private $fileCount = 0;
 private $lineCount = 0;

 public function getFileCount() { return $this->fileCount; }
 public function getLineCount() { return $this->lineCount; }
 public function setFileCount($fileCount) {
 $this->fileCount = $fileCount;
 return $this;
 }
 public function setLineCount($lineCount) {
 $this->lineCount = $lineCount;
 return $this;
 }

 /**
 * 累加
 */
 public function increaseByOther($totalCodeInfo) {
 $this->setFileCount( $this->fileCount + $totalCodeInfo->getFileCount());
 $this->setLineCount( $this->lineCount + $totalCodeInfo->getLineCount());
 return $this;
 }
}

$dirList = array();
$dirList[] = "/your/path";

$obj = new TotalCode();
$obj->main($dirList);
