php如何利用语法统计代码行数及文件数量

php如何利用语法统计代码行数及文件数量，下面编程教程网小编给大家详细介绍一下具体操作流程！

1、设置php环境变量

//Windows:
我的电脑->属性->高级系统设置->PATH 加入PHP.exe的所在目录

//Linux:
vim /etc/profile
PATH="$PATH:/root/php/bin/"

2、新增count.php文件，输入以下代码：

<?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[] = "./";
$obj = new TotalCode();
$obj->main($dirList);
?>

3、语法执行

php count.php

4、结果返回

TotalCodeInfo Object                             
(                                                
    [fileCount:TotalCodeInfo:private] => 1024
    [lineCount:TotalCodeInfo:private] => 551689
)
