新版本php 5.3安装中short_tag的问题

  今天打算装了最新版本的php 5.3.3玩下，按原来的步骤安装后，
发现运行phpinfo居然显示空白，能查看出php的代码，搞到以为我什么地方错了，
后来一看，原来是新版本的php，对short_tag有严格的要求了，

请看；
This directive determines whether or not PHP will recognize code between
; <? and ?> tags as PHP source which should be processed as such. It's been
; recommended for several years that you not use the short tag "short cut" and
; instead to use the full <?php and ?> tag combination. With the wide spread use
; of XML and use of these tags by other languages, the server can become easily
; confused and end up parsing the wrong code in the wrong context. But because
; this short cut has been a feature for such a long time, it's currently still
; supported for backwards compatibility, but we recommend you don't use them.
; Default Value: On
; Development Value: Off
; Production Value: Off

在php 5.3.3下，只有两个php-development.ini和php-product.ini,
而我刚好拿了development这个ini来改，看到了吧，这个时候
short_open_tag = Off的，而我的phpinfo代码中，
是<?  ?>的，所以当然不支持拉，
所以把short_open_tag = On就没问题了
