Nested IF statement PHP
<p>after a bit of adivce -I have a rather lengthy chunk of nested if statement, and I'm looking at ways I can refine it and make it more efficient. I did think of a switch - but I can't see how I could split this up.</p>

<p>Any thoughts appreciated</p>

<pre><code>  $portfolioItems [$i] = array(//assign vars into array
  'imagePath' =&gt; '/sites/jda_redev/'.$myrow_home-&gt;path.'/thumbs/thumbs_'.$myrow_home-&gt;filename,
  'altText' =&gt; $myrow_home-&gt;alttext,
  'description' =&gt; $myrow_home-&gt;description,
  'client' =&gt; $extra_client-&gt;field_value,
  'job' =&gt; $extra_job-&gt;field_value,
  'channel' =&gt; $extra_channel-&gt;field_value,
  'channeltwo' =&gt; $extra_channeltwo-&gt;field_value,
  'channelthree' =&gt; $extra_channelthree-&gt;field_value,
  'channelfour' =&gt; $extra_channelfour-&gt;field_value,
  'channelfive' =&gt; $extra_channelfive-&gt;field_value,
  'sector' =&gt; $extra_sector-&gt;field_value,
  'workerone' =&gt; $extra_workerone-&gt;field_value,
  'workertwo' =&gt; $extra_workertwo-&gt;field_value,
  'gallery' =&gt; $galleryName,
  'mediaType' =&gt; $media_type-&gt;field_value,
  'videoName' =&gt; $video_name-&gt;field_value
  );

if ( $portfolioItems [$i]['imagePath'] == "" )
      {$portfolioItems [$i]['imagePath'] = " ";}
      if ( $portfolioItems [$i]['altText'] == "" )
