simple questions (<%=, error reporting)

[Digital Puer]

Hi, I'm a newbie coming from JSP (and also a lifetime of C/C++/Java), and
I was wondering if someone could help me with the following questions.

1. Does PHP have a way to display an expression or variable without
using echo? I'm particularly looking for JSP's <%= %> operator
that will allow me to embed a variable right into HTML.

2. About error reporting, I've found that the default error reporting
level doesn't report undefined variables (these are occuring, for
example, when I misspell a variable name). If I set error_reporting
in php.ini to be E_ALL, undefined variables will be reported, but I
also get a lot of undefined variable errors in HTTP_POST_VARS and the like.
Surely that has to be a happy medium?

Thank you for any help.

I think you're looking for <?=$variable? >. Example:

<b>The value is: <i><?=$value? ></i></b>

You can also use this syntax for expressions, e.g.,

<b>The value is: <i><?=($foo+5 )/$bar?></i><b>

HTH,

Try this:

error_reporting (E_ALL & ~E_NOTICE);

HTH,

Don't forget to set

short_open_tag = On
asp_tags = On

in php.ini

With short_open_tag off you have to start every piece
of PHP code with <?php

With it on you can start PHP code with <?

If you will be using your scripts on servers you do not
control, it's better to always use <?php as it will
not fail no matter what the settings are in php.ini

The last option allows you to do start php code with
<% instead of <?. I'm not sure if you must use <%php
if you keep short_open_tag off :) Try it!
