我没有在<？的wampserver中获得所需的结果。 syntax.Why？

I am using wamp server 2.0 on windows XP with PHP version 5.2.5 when I am using the following code

<?
  echo "hai";
?>

I am not getting the output. But when I am using

<?php
  echo "hai";
?>

Got the result.If I am using the first one in Linux server I got the output.One of my large project like the first one in all php pages.I want to configure with wamp.SO if first coding needs to work what can I do?

My first guess is your php.ini isn't configured for this. The parameter short_open_tag is responsible for it.

Edit your php.ini, search the following parameter and activate it (or add it when its missing there):

short_open_tag = On

More details are in the php-manual.

i'm not using wamp now, maybe you can test solution from http://www.wampserver.com/phorum/read.php?2,50473,50474#msg-50474. Wish this can help you. :)
