PHP官方網站剛剛釋出了PHP 5.1.1，離上次5.1.0版本的PHP發佈，間隔只有4天。PHP官方緊急表示，建議使用PHP5的網站最好進行升級，本站也已經更新為PHP 5.1.1。
這次PHP 5.1.1主要是為了改善5.1.0的一些bugs。
還好有推出更新，不然我快要被不斷自動重開apache、後端錯誤訊息一堆等這些新版的問題煩死了。處理完PHP後，再來就是解決有時候出線的連接資料庫過久等問題。
另外，使用PHP4的話，最新版是PHP 4.4.1，我想之後應該會再有更新版本，因為它沒有PHP 4.4.0穩定。
PHP 5.1.1主要的更新內容為：
* Disabled native date class to prevent pear::date conflict. (Ilia)
* Improved safe_mode/open_basedir checks in cURL extension. (Ilia, Jani)
* Changed reflection constants be both PHP and class constants. (Johannes)
* Added an additional field $frame['object'] to the result array of debug_backtrace() that contains a reference to the respective object when the frame was called from an object. (Sebastian)
