PHP Beginner question

[Genfors]

Hi,

I have started to follow the tutorial "Build your own Database Driven Website using PHP & MySQL - Part 3: Getting Started with PHP".

The problem i have is that the statement "<?=$_SERVER['PHP_SELF']?>" in the samplecode does not work.

If i replace it with "<?php echo($_SERVER['PHP_SELF'] ?>" it works.

What could be wrong?

Regards,

Mats

could be that short tags in php.ini is disabled.

As a good habit you shouldnt use short tags anyway.

If i replace it with "<?php echo($_SERVER['PHP_SELF'] ?>" it works.

That cannot work (typo?), since there's a paranthesis opened but no more closed.

with

<?php echo $_SERVER['PHP_SELF']; ?>

you are on the save side (if your PHP version already knows the Superglobals) .

The <? and ?> symbols can be used in an HTML or XML document to indicate some sort of code that should be interpreted by the application.

You can choose to escape from HTML in a PHP file in four different ways.

Using <?php and ?> (always available)
Using <script language="php"> and </script> (always available)
Using <? and ?> (available by default, but can be disabled)
Using <% and %> (available by default, but can be disabled)

Chances are, parsing PHP within <? and ?> tags is disabled in the php.ini file on your server.

These are called "short tags" by PHP. Short tags are discouraged, because not all php.ini files support them and because they may conflict with a future technology which also uses <?

Ok, thanks.

And yes it was a typo, it should be "<?php echo($_SERVER['PHP_SELF']); ?>"

ecause they may conflict with a future technology which also uses <?

XML for example. Writing XHTML 1.1 with short_tags = on can be quite a pain.
