This article mainly introduces you to the relevant knowledge about PHP statistics, and talks about how to use PHP to count the number of lines of code and the number of files. I hope it will be helpful to friends in need!

Use PHP to count the number of lines of code and the number of files

Sometimes we need to count the number of lines of code and the number of files (such as applying for a soft copy), we can use PHP statistics.

First set the PHP environment variables

Windows:

My Computer->Properties ->Advanced system settings->PATH Add the directory where PHP.exe is located

Linux Set environment variables:

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

In the project file Execute the following code in the folder

<?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) {

        print_r($totalCodeAll);
