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 

;  http://php.net/short-open-tag 


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
