WEBシステム開発/待望のPHP5.3がリリースされましたPHP6への準備が始まる

6/30日に待望のPHP5.3がリリースされています。

RC版が頻繁にバージョンアップされていたので、もうそろそろかな～っと
思っていた矢先に！

PHP5.3はPHP6への移行をスムーズにする為、大幅な変更をされている見たいですが
何といっても、処理の高速化が楽しみですね。

稼働中の負荷が大きいサーバーでテストしたいと思います。



主な機能追加は下記

* Support for namespaces
* Late static binding
* Lambda Functions and Closures
* Syntax additions: NOWDOC, ternary short cut “?:” and jump label (limited goto), __callStatic()
* Under the hood performance improvements
* Optional garbage collection for cyclic references
* Optional mysqlnd PHP native replacement for libmysql
* Improved Windows support including VC9 and experimental X64 binaries as well as portability to other supported platforms
* More consistent float rounding
* Deprecation notices are now handled via E_DEPRECATED (part of E_ALL) instead of the E_STRICT error level
* Several enhancements to enable more flexiblity in php.ini (and ini parsing in general)
* New bundled extensions: ext/phar, ext/intl, ext/fileinfo, ext/sqlite3, ext/enchant
* Over 140 bug fixes and improvements to PHP, in particular to: ext/openssl, ext/spl and ext/date

This release also drops several extensions and unifies the usage of internal APIs. Users should be aware of the following known backwards compatibility breaks:

* Parameter parsing API unification will cause some functions to behave more or less strict when it comes to type juggling
* Removed the following extensions: ext/mhash (see ext/hash), ext/msql, ext/pspell (see ext/enchant), ext/sybase (see ext/sybase_ct)
* Moved the following extensions to PECL: ext/ming, ext/fbsql, ext/ncurses, ext/fdf
* Removed zend.ze1_compatibility_mode
