Body
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. 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 Nodes in xml file (yeah it's only the first tag, but you get the idea) <pre><code><set1score> <set2score> <set3score> <set4score> <set5score> <set6score> <set7score> <set8score> <set9score> <set10score> <set11score> </code></pre> xmlParse.php <pre><code><?php class xmlParse { private $xmlFile; public function __construct($xmlFile) { $this->xmlFile = $xmlFile; } private function xmlVerify($p) { return pathinfo($p,PATHINFO_EXTENSION)=='xml'; } public function encodeJSON() { if($this->xmlVerify($this->xmlFile)) { $xml = simplexml_load_file($this->xmlFile); return json_encode($xml->children()); } else { return ('<script>alert(\'error with xml file validation\');</script>'); } } } ?> </code></pre> studentInformation.php <pre><code><?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->decodeJSON($this->encodeJSON($this->xmlFile))->student as $v) { $output .= "<tr>"; $output .= "<td>" . $v->lname . "</td>"; $output .= "<td>" . $v->fname . "</td>"; $output .= "<td>" . $v->set($count)score . "</td>"; //PROBLEM HERE!!!!! $output .= "</tr>"; $count++; } return $output; } } ?> </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
