php 遍历目录，生成目录下每个文件的md5值并写入到结果文件中
实例代码：
<?php /** * @author Administrator * */ class TestGenerate { public static $appFolder = ""; public static $ignoreFilePaths = array ( "xxxx/xxx.php" ); public static function start() { $AppPath = "E:\\myApp"; TestGenerate::$appFolder = $AppPath; $destManifestPath = "E:\\temp2\\dest.md5.txt"; // dest file handle $manifestHandle = fopen ( $destManifestPath, "w+" ); // write header TestGenerate::writeMaifestHeader ( $manifestHandle ); // write md5 TestGenerate::traverse ( $AppPath, $manifestHandle ); // write footer TestGenerate::writeMaifestFooter ( $manifestHandle ); // close file fclose ( $manifestHandle ); } /** * 遍历应用根目录下的文件，并生成对应的文件长度及md5信息 * * @param unknown $AppPath * 应用根目录，如：xxx/xxx/analytics * @param string $destManifestPath * 生成的manifest文件存放位置的文件句柄 */ public static function traverse($AppPath, $manifestHandle) { if (! file_exists ( $AppPath )) { printf ( $AppPath . " does not exist!" ); return; } if (! is_dir ( $AppPath )) { printf ( $AppPath . " is not a directory!" ); return; } if (! ($dh = opendir ( $AppPath ))) { printf ( "Failure while read diectory!" ); return; } // read files while ( ($file = readdir ( $dh )) != false ) { $subDir = $AppPath . DIRECTORY_SEPARATOR . $file; if ($file == "." || $file == "..") { continue; } else if (is_dir ( $subDir )) { // rescure TestGenerate::traverse ( $subDir, $manifestHandle ); } else { // Sub is a file. TestGenerate::writeOneFieToManifest ( $subDir, $manifestHandle ); } } // close dir closedir ( $dh ); } /** * 写一个文件的md5信息到文件中 * * @param unknown $filePath * @param unknown $fileHandle */ public static function writeOneFieToManifest($filePath, $fileHandle) { if (! file_exists ( $filePath )) { continue; } $relativePath = str_replace ( TestGenerate::$appFolder .
