Using variables deinfed later

pat

Is it possible in anyway to use a variable that is initialied *after*
its
use.

What I am trying to achieve is the following, i.e. ,using a PHP
variable that is initialised later to display a HTML Title, code
snippet below. As it
stands at present nothing is echoed!

<html>
<head>
<title><?php echo ($strTitle);?></title>
</head>
<body>
......
<?php
....
$strTitle= getTitle();
...
?>

Wow that's some task! Like asking to be buried before you're born ;)

Silly question time, what results to you expect?

In short, your example below _will_ work with in PHP4 (not 5 though AFAIK)
but $strTitle will be empty in the first instance. You should still define
the variable as below, but I suspect this isn't strictly the answer you're
looking for or rather, hoping for.
<?php
$strTitle = '';
?> <html>
<head>
<title><?php echo ($strTitle);?></title>
</head>
<body>
......
<?php
....
$strTitle= getTitle();
...
?>

Oops, should have added:

If I understand you correctly, you want the title to display but you're
actualy getting the title half way through the script. You maybe able to
do this with output buffering (see ob_start() and other relative functions
on php.net for more info) but it's something I don't use very often at
all, so can't really point you in a better direction than the manual
unfortunately.

Hope this sort of helps though.

Regards,

Ian

Hm, time travel variables - sounds like this could work nicely with the
mythical COME FROM command (opposite of GOTO) to write truly evil programs.

But seriously - no.

Try the output buffer functions:

http://us2.php.net/manual/en/ref.outcontrol.php

1) Turn on output buffering.

2) Do stuff.

3) Flush buffer.

Yes you can -as explained by others- using output-buffering. But it's not
exactly desirable programming style. Try to avoid constructions like this.
