/** * Returns a new (child of) sfFilebasePluginFile. It returns an instance, * not regarding if the file exists or not.

It * is probably more confusing for windows users where files are mostly * identified by its extension. * * If the dir exists, you'll get a sfFilebasePluginDirectory. * * @example $filebase->getFilebaseFile('path/to/directory') retrieves a dir * if it exists in FS, or a sfFilebaseFile if not. * * @example Creating a new file: * $new_file = $filebase->getFilebaseFile('path/to/new/file.txt'); * $filebase->touch($new_file); * In Short: $filebase->touch('path/to/new/file.txt'); * * @example Short way retrieving files: * foreach ($filebase AS $file) ... * with ArrayAccess: * $file = $filebase['/path/to/file']; * * @todo Implement (sym)link handling. * @param string | sfFilebasePluginFile $filename * @return sfFilebasePluginFile */ public function getFilebaseFile($filename) { if (is_string($filename)) { //$filename = sfFilebasePluginUtil::unifySlashes($filename); if (strlen($filename) > 0) { if (sfFilebasePluginUtil::isAbsolutePathname($filename)) { $filename = new sfFilebasePluginFile($filename, $this->filebase); } else { $filename = new sfFilebasePluginFile($this->getPathname() .
