PHP 统计代码行数小工具

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 
	 */
