PHP实现统计代码行数小工具

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);
