Question

I am trying to play with php, I aint very good. But I figured its about time I started playing with it

What I have is say a page called ascr

Its filename is acsr.php

I have created a global php include, so I can play with different vars and include them dynamically.

So I have made a var called $shorttag = “acsr”;

On my page I would like to use that shorttag to fire images and classes etc.

So for an image I want to display

img src="/img/<?php $shorttag; ?>.jpg"

and in other places perhaps,

div class="<?php $shorttag; ?>"

Is this the CORRECT way of doing stuff like this ?

Example.

say I have folder with image in it called acsr.jpg

On my dynamic page I want to echo that image, but instead of using filename, I want to pull it in based on my php var , in this case its called $shorttag so essentially, $shorttag=acsr , and therefore I can spew out something like:

<?php $shorttag; ?>.jpg

( code above more than likely wrong )

But the result gives me ascr.jpg

Answer 1

You need to echo it so it is actually output.

div class="<?php echo $shorttag; ?>"

img src="/img/<?php echo $shorttag; ?>.jpg"

If PHP is configured to use short_open_tag (which is not usually recommended since it may be turned off on some servers)

img src="/img/<?= $shorttag ?>.jpg"

The rules change for PHP 5.4 and later, where you can use <?= ?> without having to turn on short_open_tag:

This directive also affected the shorthand <?= before PHP 5.4.0, which is identical to <? echo. Use of this shortcut required short_open_tag to be on. Since PHP 5.4.0, <?= is always available.
