　　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 (!
