Fetch specific field from a MySQL result array - php

Question

I’m trying to retrive the field media_file from the first line of the query.
I don’t figure how to do that. I’ve tried several times to get it by calling the multidimensional array $pages[0]['media_file'] with no success.
I’m trying to have the first image of a series bigger and then append the other thumbs.
Here the page that we are talking about: http://www.svarnet.it/index.php?/works/svarnet-dream/
this is the code:
function createExhibit()
{
$OBJ =& get_instance();
global $rs;
$pages = $OBJ->db->fetchArray("SELECT *
FROM ".PX."media, ".PX."objects_prefs
WHERE media_ref_id = '$rs[id]'
AND obj_ref_type = 'exhibit'
AND obj_ref_type = media_obj_type
ORDER BY media_order ASC, media_id ASC");
$s = "<div id='text-container'>\n";
$s .= $rs['content'];
$s .= "</div>\n";
$s .= "\n<div class='cl'><!-- --></div>\n";
if (!$pages) return $s;
foreach ($pages as $height)
{
$height = getimagesize(DIRNAME . GIMGS . "/th-$height[media_file]");
$find_smallest_height[] = $height[1];
}
sort($find_smallest_height, SORT_NUMERIC);
rsort($find_smallest_height);
$lowest = array_pop($find_smallest_height);
$i = 1; $a = '';
foreach ($pages as $go)
{
$a .= "\n<a class='group' rel='group' href='" . BASEURL . GIMGS . "/$go[media_file]' title='$go[media_title]'><imgXXX src='" . BASEURL . GIMGS . "/th-$go[media_file]' alt='$go[media_caption]' height='80px' /></a>\n";
$i++;
}
// images
$s .= "<div id='img-container'>\n";
// //////////////// HERE I WANT TO INSERT THE FIRST IMAGE OF THE QUERY
$s .= "<imgXXX src='" . BASEURL . GIMGS . $pages['media_file'] . "' alt='$pages[media_title]' />";
// THEN APPEND THE OTHERS IN THUMB FORMAT
$s .= $a;
$s .= "</div>\n";
return $s;
}
Thanks in advance!

You cannot access your $height['media_file'] variable inside double quoted strings like that. You will either use the complex syntax with curly braces:
"/th-{$height['media_file']}"
"/th-${height['media_file']}"
Or you use the string concatenation operator .:
"/th-".$height['media_file']
