Question

I have a PHP if/else statement. This is the code I’m trying to echo under an else condition.

<?php $locked = ForumData::is_topic_locked($post->topic_id);
            if ($locked->topic_locked == 1) {echo '<td align="right"><font color="#FF0000">Topic Locked</font><td>';}
            else { 
            echo '<td align="left"><a href="'.url('Forum/create_new_post?topic_id='.$post->topic_id.'&forum_id='.$post->forum_id.'').'"><img src="<?php echo SITE_URL?>/lib/skins/flyeuro/images/forums/t_reply.gif"/></a></td>'; }
            ?>

The bit I’m interested to echo is this.

<img src="<?php echo SITE_URL?>

If I try this… ‘echo SITE_URL’

Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';'

But this doesn’t parse the image, and if I try parsing anything else, it’s giving me parsing errors, which I can’t fix?

How can I therefore produce an echo inside another echo?

Answer 1

why did you open a <?php tag again, you are already in echo line?

echo '<td align="left"><a href="'.url('Forum/create_new_post?topic_id='.$post->topic_id.'&forum_id='.$post->forum_id.'').'"><img src="'.SITE_URL.'/lib/skins/flyeuro/images/forums/t_reply.gif"/></a></td>';

and what is SITE_URL? Is that a variable, did you forget to put $?

echo prints out the string that you gave as parameter,

echo "foo";

As @hakre mentioned about it, . is used to concatenate strings.

$var = "foo"."bar";  //foobar

So you can use it in echo line,

$var = "foo"."bar";  //foobar
echo "foo "."bar ".$var // foo bar foobar

And It’s not important weather variable defined as a string. It would be a constant variable.

define('SITE_URL', 'localhost:8080/phpvms'); 
echo "my website URL is ".SITE_URL; //my website URL is localhost:8080/phpvms
