PHP array only using the first line of text area for 'Get Meta Tags' Function

I am fairly new to PHP so please bear with me :)

What I am trying to do if place URL's into a text area, then pull in the meta data for each.

I have made the script, but when I place more then one URL into the text area it only returns data for the last URL entered, I thought maybe you guys can help me :)

<form method="POST">
 <textarea name="TAData">
 </textarea>
 <input type="submit" value="submit"/>
 </form>
 
 <div id="checkboxes">
 <input type="checkbox" name="vehicle" value="PR" /> Show me the PR<br />
 <input type="checkbox" name="vehicle" value="KW Tag" /> Show me the KW tag<br />
 <input type="checkbox" name="vehicle" value="Title Tag" /> Show me the Title tag<br />
 </div>
 <div id="checkboxes">
 <input type="checkbox" name="vehicle" value="1stH1" /> Show me the 1st H1<br />
 <input type="checkbox" name="vehicle" value="2ndH1" /> Show me the 2nd H1 tag<br />
 <input type="checkbox" name="vehicle" value="SeedKW" /> Show me Seed KW's<br />
 </div>
 
 <div id="nofloat"></div>
 
 <?php
 
 //make the array 
 $TAarray = explode("\n", strip_tags($_POST['TAData'])); 
 
 foreach ($TAarray as $key => &$line) { $line = trim($line); }
             // get the meta data for each url
             $tags = get_meta_tags($line);
 
 unset($tags["content-type"]);
 unset($tags["page-type"]);
 unset($tags["page-topic"]);
 unset($tags["audience"]);
 unset($tags["content-language"]);       
 
             echo '<tr>';
             foreach ($tags as $meta)        
             {
                     echo '<td>' . $meta . '</td>';
             }
             echo '</tr>';
 
 ?>
