詳細描述

Alternative implementation of the glob() function, since the latter is only available in php versions 4.3 or higher and many many hosts have not updated yet. Original glob function: http://www.php.net/manual/en/function.glob.php. Original fnmatch function: http://www.php.net/manual/en/function.fnmatch.php.

The class is capable of detecting the version of php and using the native (and probably faster) version instead of the custom one.

定義在 glob.class.php 檔案之第 24 行.

建構子與解構子說明文件

Glob::Glob (  $  folder = ".", $  pattern = "*", $  flags = 0 )  [static]

This function checks wether we're running a version of php at least or newer than 4.3. If its newer, then we will use the native version of glob otherwise we will use our own version. The order of the parameters is not the same as the native version of glob, but they will be converted. The flags parameter is not used when using the custom version of glob. 參數: folder  The folder where would like to search for files. This function is not recursive. pattern  The shell pattern that will match the files we are searching for. flags  This parameter is only used when using the native version of glob. For possible values of this parameter, please check the glob function page. 傳回值: Returns an array of the files that match the given pattern in the given folder or false if there was an error. 定義在 glob.class.php 檔案之第 43 行. 參考 myGlob(). { if( function_exists("glob")) { // call the native glob function with parameters $fileName = $folder; if( substr($fileName, -1) != "/" ) $fileName .= "/"; $fileName .= $pattern; return glob( $fileName, $flags ); } else { // call our own implementation return Glob::myGlob( $folder, $pattern ); } }

Glob::fnmatch (  $  pattern, $  file )  [static]

Front-end function that does the same as the glob function above but this time with the fnmnatch version. Checks the php version and if it is at least or greater than 4.3, then we will use the native and faster version of fnmatch or otherwise we will fall back to using our own custom version. 參數: pattern  The shell pattern. file  The filename we would like to match. 傳回值: True if the file matches the pattern or false if not. 定義在 glob.class.php 檔案之第 71 行. 參考 myFnmatch(). 被參考於 myGlob(). { if( function_exists("fnmatch")) { // use the native fnmatch version return fnmatch( $pattern, $file ); } else { // otherwise, use our own return Glob::myFnmatch( $pattern, $file ); } }

Glob::myFnmatch (  $  pattern, $  file )

Our own equivalent of fnmatch that is only available in php 4.3.x. Based on a user-contributed code for the fnmatch php function here: http://www.php.net/manual/en/function.fnmatch.php 定義在 glob.class.php 檔案之第 130 行. 被參考於 fnmatch(), 及 UploadValidator::validate(). { for($i=0; $i<strlen($pattern); $i++) { if($pattern[$i] == "*") { for($c=$i; $c<max(strlen($pattern), strlen($file)); $c++) { if(Glob::myFnmatch(substr($pattern, $i+1), substr($file, $c))) { return true; } } return false; } if($pattern[$i] == "[") { $letter_set = array(); for($c=$i+1; $c<strlen($pattern); $c++) { if($pattern[$c] != "]") { array_push($letter_set, $pattern[$c]); } else break; } foreach ($letter_set as $letter) { if(Glob::myFnmatch($letter.substr($pattern, $c+1), substr($file, $i))) { return true; } } return false; } if($pattern[$i] == "?") { continue; } if($pattern[$i] != $file[$i]) { return false; } } return true; }

Glob::myGlob (  $  folder = ".", $  pattern = "*" )

Our own implementation of the glob function for those sites which run a version of php lower than 4.3. For more information on the function glob: http://www.php.net/manual/en/function.glob.php Returns an array with all the files and subdirs that match the given shell expression. 參數: folder  Where to start searching. pattern  A shell expression including wildcards '*' and '?' defining which files will match and which will not. 傳回值: An array with the matching files and false if error. 定義在 glob.class.php 檔案之第 94 行. 參考 fnmatch(). 被參考於 TemplateSandbox::checkForbiddenFiles(), File::deleteDir(), FileFinder::find(), Glob(), 及 Captcha::purgeOld(). { // Note that !== did not exist until 4.0.0-RC2 // what if the temp folder is deleted? or $folder is not exist? then will raise // ugly error or warning message. so first check if $folder readable if( !file_exists( $folder )) return Array(); if ( $handle = opendir( $folder )) { $files = Array(); while (false !== ($file = readdir($handle))) { if( $file !="." && $file != ".." ) // ignore '.' and '..' if( Glob::fnmatch($pattern,$file)) { if( $folder[strlen($folder)-1] != "/") $filePath = $folder."/".$file; else $filePath = $folder.$file; array_push( $files, $filePath ); } } closedir($handle); } else return Array(); return $files; }
