想試試cakephp，將其解壓到apache的htdocs目錄後，訪問出現strtotime調用問題、時區設定問題
下面是訪問cakephp目錄下的index.php瀏覽器給出的提示：

PHP code

Warning (2): strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

我然後看了下它所提示的原始碼：
