variables / scope / includes 2

[1DMF]

Hi,

I seem unable to access a variables I created from within my include file?

index.php

<?php

$title_tag = 'This is a title ';
 
include('includes/header.php');

?>

header.php

<title><?php $title_tag ?></title>

What am I doing wrong?

Thanks,
1DMF

it's OK, found a way of doing it

$SYSN['title'] = 'XYZ'

 and then 

<?=$SYSN['title']?>

Just to clarify, you were simply not outputting the value at all. You need to use the equal sign with the PHP opening tags or an echo or print.

Placing a variable inside PHP tags does nothing to it.

<?php $myVar ?>

<?php echo $myvar; ?>

OIC - thanks Phil.

I don't do PHP normally, so am a total noobie!

you may have seen this notation in older examples (and will start seeing it again now that php 5.4.0 has enabled this as default functionality, irrespective of ini settings)

<?= $value ?>

this is synonymous with

<?php echo $value; ?>

until recently this was not regarded as good practice because it required that php had short_tags turned on. and short_tags were discouraged because of xml compatibility. however from 5.4.0 using the <?= short cut is no longer discouraged.

cool, thanks jpadie.

I guess short_tags are on by default in the windows environment I am using, as it worked first time without issue.

they are indeed on by default. although I remember that they weren't for at least some versions.
