PHP Simple Html Dom Parser - "double" dimension arrays - php

Question

I realize there are no multi-dimension arrays with PHP, however here is the issue.
I have this inside a for ($fix) loop:
$html->find('tr[class] td', $fix);
Now in a row there are more than one td being grabbed, so say the first one holds the username
I would like to grab the username, and this is what I'm trying but its not working:
$username = $html[0];
I also tried something like this
$username = $html->find('tr[class] td', $fix, 0)
Neither of these works, what should I be using?
Full Code:
<?php
include('simple_html_dom.php');
$q=$_REQUEST["q"]; $hint="";
$ctx = stream_context_create(array(
'http' => array(
'timeout' => 15
)
)
);
$html = file_get_html('http://www.example.com/index.php?q=' . urlencode($q), 0, $ctx);
$tr = $html->find('tr');
// lookup all hints from array if $q is different from ""
$fix = 0;
if ($q !== "") {
$q=strtolower($q); $len=strlen($q);
foreach($tr as $name) {
$fix++;
if($fix > 2) {
$selector = $html->find('tr[class] td');
$username = $selector[$fix][0]->plaintext;
$name = $selector;
$username_fix = str_replace ('.',"",$username);
if ($hint==="") {
$hint='<tr>
<td>' . $name->plaintext . '<br />' . $username . '</td>
<td> </td>
<td><button type="button" class="btn btn-sm btn-primary" data-toggle="modal" data-target="#M' . $username_fix . '">This is me!</button></td>
<div class="modal fade" id="M' . $username_fix . '" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Yo</h4>
</div>
<div class="modal-body">
<p>Hey…' . $name->plaintext . '</p>
</div>
<div class="modal-footer">

<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</tr>';
} else {
$hint .='<tr>
<td>' . $name->plaintext . '<br />' . $username . '</td>
<td> </td>
<td><button type="button" class="btn btn-sm btn-primary" data-toggle="modal" data-target="#M' . $username_fix . '">This is me!</button></td>
<div class="modal fade" id="M' . $username_fix . '" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

</div>
</div>
</div>
</div>
</tr>';
}
}
}
}
// Output "no suggestion" if no hint were found
// or output the correct values
if($hint === "") {
echo 'My records indicate you a liar!';
} else {
echo '
<table class="table table-striped table-bordered">
<tr>
<th style="min-width:20%;">Name</th>
<th>Department</th>
<th width="9%"> </th>
</tr>
';
echo $hint;
echo '</table>';
}
?>
still dirty as ever, would like it functional first
