本篇文章主要给大家介绍有关PHP统计的相关知识，聊聊怎么用PHP来实现统计代码行数以及文件数量，希望对需要的朋友有所帮助！

用PHP统计代码行数和文件数量

有时候我们需要统计代码行数和文件数量（比如申请软著），我们可以用 PHP 进行统计。

首先设置 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 设置环境变量:

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

登录后复制

在项目文件夹里执行以下代码

<?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);
?>

结果

执行代码

php count.php

登录后复制

成功

TotalCodeInfo Object                             
(                                                
    [fileCount:TotalCodeInfo:private] => 1094    
    [lineCount:TotalCodeInfo:private] => 419702  
)
