关于typo3

欢迎访问: www.ptcms.cn　　
Typo3内容管理系统,是基于PHP4/PHP5+MYsql的内容管理系统(框架)(CMS/CMF),兼容PHP4和PHP5.数据库系统除Mysql之外,也能运行于Oracle, MS-SQL, ODBC, LDAP 等其它数据库系统,支持Typo3的服务器系统:Apache或者IIS架设的服务器.

　　Typo3当前最新版本:4.12

　　Typo3未来版本PHP语言要求情况:

　　从Typo3 4.20起:Typo3将全面移至PHP5.

　　从Typo3 5.0起:Typo3将全面移至PHP6.

　　简介:

　　typo3是一个很出名的开源CMS.Typo3是开源内容管理系统(CMS)和内容管理框架(CMF)的领导性品牌之一，是一个真正高端企业级的产品；由于其不是面向低端用户的产品，因而在国内影响相当有限。 Typo3主要是面向中高级php水平的开发者，但经过一番学习也适合一般不懂编程的用户使用。

　　Typo3, 开源里边最强大的，也是最接近商业化用途的网站内容管理框架(CMF)之一。基于PHP和MySQL数据库。这是一个非常复杂的内容框架程序，要熟练掌握应用它，是需要一定的时间的。在它的官方网站介绍中称，该程序是主要对开发者，专业级人士设计的，如果你是一个专业人士，要掌握它可能需要两周到一个月时间。如果你一个一般的建站的用户，可能需要两个月。

　　Typo3系统需求:

　　System Requirements

　　TYPO3 is a web application programmed in PHP, but it is not an application in the usual sense (Windows, Mac or Linux). In other words: TYPO3 is installed on a webserver alongside PHP, and you work with it through a web browser, like Internet Explorer or Mozilla Firefox, or you "run" TYPO3 on the server.

　　To run TYPO3 successfully there are some requirements for both server and client (user) that must be met.

　　Webserver

　　Operating System: Unix (eg Linux), Windows or Mac

　　Webserver: Webserver Apache, IIS

　　Middleware: PHP4 or PHP5 (Note: Starting with TYPO3 4.2.0, all releases will require PHP5!)

　　Database: MySQL or any other database system supported by the TYPO3 DBAL (e.g. Oracle, Postgres and a lot of others)

　　Hardware: A normal webserver setup will do, with some modern CPU and at least 256 MB Ram. As with all database-driven applications, more RAM is advisable though.

　　High-performance setups will want to make use of load-balancing and use the staging/static HTML-export capability of TYPO3. Check for the static file setup in the mailing list archives and in the installation script to get started.

　　Optional - but recommended - webserver software extras:

　　GraphicsMagick (standalone) (ImageMagick will work, too)

　　GDlib/Freetype (compiled with PHP)

　　zlib (compiled with PHP)

　　Apache with mod_gzip/mod_rewrite

　　A PHP-cache (eg. PHP-accelerator / Zend Accelerator, UNIX only)

　　Further individual extensions may require further software to be available. For instance the AWstats extension is based on Perl and the Indexed Search engine uses "pdftotext" and "catdoc" for indexing PDF and Word documents.

　　Client (user)

　　Recommended: Mozilla Firefox on any OS, Internet Explorer 5+ on Windows

　　Required: Any graphical browser on any OS (IE, Opera, Safari, Konqueror on Windows, Unix, Mac)

　　Hardware: Relatively modern computer

　　Important notice about memory consumption

　　Currently there are parts in TYPO3 requiring more than the usual 8MB memory configured in the php.ini files of default installations. In many cases this is not at all a problem since that memorylimit is ignored unless support for it has been compiled into PHP (or if you are running PHP as CGI).

　　But the bottom line is - configure for at least 16 MB memory (we recommend to use 32 MB or even more).

　　We are always working on memory optimizations, but certain parts of TYPO3 will just require more than 8MB of memory.

　　In general, you won't be happy with TYPO3 on your old 486 ;-)
