Tag <? PHP problem

I work with legacy code that someone left, and my task is to redeploy the code. I am using Windows Server 2003, Apache 2.0.63 and PHP 5.2.10.

This does not work. At least not as I expected it to work. Call it bugs if you want.

When checking, I had a suspicion that this code (which appears many times in the application) is the culprit.

  & $ this->

To illustrate the problem, I reproduce this code:

  <? php
        phpinfo ();
        // $ variable = & $ this-> request;
     ?>

The above code is executed beautifully and as expected. However, if I changed the code to:

  <?
        phpinfo ();
        // $ variable = & $ this-> request;
     ?>

The code does not work correctly and produces this result on the screen instead, which, of course, is completely undesirable and unexpected.

  request;  ?>

Now the code is littered with the same code as above, and thus the application now displays a screen similar to this:

  request;  $ user = & $ this-> user;  // This is comment return false;  ?>

for code that reads like:

  <?
         $ request = & $ this-> request;
         $ user = & $ this-> user;
         // This is comment
         return false;
     ?>

I tried to change every <? with <? php when & $ this-> returns its ugly head, but most of the time it introduces a new error.

I reinstalled PHP and Apache, even using a different version of PHP (5.2.6), and it still won't work. I deployed the code in my local host (Mac OS X, PHP 5.2.8 and Apache 2.0.63) and it worked without hassle.

Please, no one, more than enough enlightenment.

In php.ini you need to install the following directive:

short_open_tag = On

From manual :

Reports whether the short form ( <? ?> ) Of an open PHP tag ...

If you have time on your hands, you may want to replace all those short tags with <? to full-length <?php , for better portability (see what just happened to you? :)

my recommendation is not to use open tags, because it can interfere with <?xml codes. I also had this problem before, just replace all <?php with <? and then again all <? on <?php .

So you do not get any

 <? <-- one space after the '?'

and

 <?php <-- one space after the 'p'

hope this helps ...

If you want to use short tags: ("<?")

they must be included in php.ini. See Link.
