PHP: echo heredoc from another script

Question

I am having trouble echoing out heredoc statements from one php file into another. I have one script which is used to retrieve API database information and then format that information into a heredoc to echo the information into the index.php page. The code that I have is:

while($artist_info = $artist_details_resource->fetch_assoc()){
   $artist = <<<DOC
             <img src="{$artist_info['image_url']}" alt="$artist_info['artist_name']" />
             <p>{$artist_name}</p>
DOC;
}

And in the index.php script I start a php clause on the place I want this heredoc to print. The code for that is:

<?php
  if($artist){
     echo $artist;
  }
?>

However this only prints the last heredoc string from the while loop, and not echoing out every heredoc through each iteration.

Did you try to print it from the same script? – Your Common Sense Jan 01 '13 at 16:21 — Your Common Sense, Jan 01 '13 at 16:21
yes even on the same script it prints only the last element – Human Jan 01 '13 at 16:22 — Human, Jan 01 '13 at 16:22
Isn't this herodoc missing ending DOC – Hanky Panky Jan 01 '13 at 16:23 — Hanky Panky, Jan 01 '13 at 16:23
your ending DOC is outside the codeblock by the way – P1nGu1n Jan 01 '13 at 16:36 — P1nGu1n, Jan 01 '13 at 16:36

Why would it? You aren't echoing it in a loop, nor you are concatenating the string. You're overwriting the string on every iteration.

while($artist_info = $artist_details_resource->fetch_assoc()){
   $artist .= <<<DOC
             <img src="{$artist_info['image_url']}" alt="$artist_info['artist_name']" />
             <p>{$artist_name}</p>
}

Note the .=

Of course this only prints the last string, because you use $artist = <<<DOC so you overwrite value of the $artist variable in every loop.

Try $artist .= <<<DOC or put it into array: $artists[] = <<<DOC
