<?php를 하면 잘되는데
<? 를 그냥하면 즉.. php를 뺴면 안되는경우가 있다
이건 php.ini의 short_open_tag = Off를
On으로 바꿔줘야한다.
다음의 그 옵션에 대한 설명이다.
; 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
