php how to dynamically change variable name?
<p>I have a script that pulls out XML information then puts it into JSON format. I am trying to change the variable name as I put everything into a table for vewing after the json is decoded.</p>

<p>For instance, there are eleven scores that will be listed and rather than write out all eleven I wanted to dynamically change the name as the loops happens. The problem line I am having is in the studentInformation.php file, I put a comment next to it to make it easier to spot. Hopefully I have explained my issue well enough :P</p>

<p>Nodes in xml file (yeah it's only the first tag, but you get the idea)</p>

<pre><code>&lt;set1score&gt;
&lt;set2score&gt;
&lt;set3score&gt;
&lt;set4score&gt;
&lt;set5score&gt;
&lt;set6score&gt;
&lt;set7score&gt;
&lt;set8score&gt;
&lt;set9score&gt;
&lt;set10score&gt;
&lt;set11score&gt;
</code></pre>

<p>xmlParse.php</p>

<pre><code>&lt;?php
class xmlParse
{   
    private $xmlFile;

    public function __construct($xmlFile)
    {
        $this-&gt;xmlFile = $xmlFile;
    }
    private function xmlVerify($p)
    {
        return pathinfo($p,PATHINFO_EXTENSION)=='xml';
    }
    public function encodeJSON()
    {
        if($this-&gt;xmlVerify($this-&gt;xmlFile))
        {
            $xml = simplexml_load_file($this-&gt;xmlFile);
       return json_encode($xml-&gt;children());
        }
        else
        {
            return ('&lt;script&gt;alert(\'error with xml file validation\');&lt;/script&gt;');
        }
    }
}
?&gt;
</code></pre>

<p>studentInformation.php</p>

<pre><code>&lt;?php
class studentInformation extends xmlParse
{
    private $xmlFile;

    public function __construct($xmlFile)
    {
        parent::__construct($xmlFile);
    }
    private function decodeJSON($i)
    {
        $j = json_decode($i);
   return $j;
    }
    public function getStudentInformation()
    {
        $output = '';
   $count = 1;
   foreach($this-&gt;decodeJSON($this-&gt;encodeJSON($this-&gt;xmlFile))-&gt;student as $v)
        {
       $output .= "&lt;tr&gt;";
       $output .= "&lt;td&gt;" . $v-&gt;lname . "&lt;/td&gt;";
       $output .= "&lt;td&gt;" . $v-&gt;fname . "&lt;/td&gt;";
       $output .= "&lt;td&gt;" . $v-&gt;set($count)score . "&lt;/td&gt;"; //PROBLEM HERE!!!!!
       $output .= "&lt;/tr&gt;";
       $count++;
   }
   return $output;  
}
}
