HTML Dom code not running - php

Question

I am trying to create a script that extracts text from a website table and displays it via php. When I run it on this address :
http://lmvz.anofm.ro:8080/lmv/detalii.jsp?UNIQUEJVID=50/01/1150001435/1&judet=50
It turns out empty. Is there something wrong with the code? And how can I fix / improve it?
<?php
include_once('simple_html_dom.php');
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
// Start a cURL resource
$ch = curl_init();
// Set options for the cURL
curl_setopt($ch, CURLOPT_URL, 'http://lmvz.anofm.ro:8080/lmv/detalii.jsp?UNIQUEJVID=50/01/1150001435/1&judet=50'); // target
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // provide a user-agent
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow any redirects
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return the result
// Execute the cURL fetch
$result = curl_exec($ch);
// Close the resource
curl_close($ch);
// Output the results
echo $result;
function scraping() {
// create HTML DOM
$html = file_get_html('http://lmvz.anofm.ro:8080/lmv/detalii.jsp?UNIQUEJVID=50/01/1150001435/1&judet=50');
// get article block
if($html && is_object($html) && isset($html->nodes)){
foreach($html->find('/html/body/table') as $article) {
// get title
$item['titlu'] = trim($article->find('/html/body/table/tbody/tr[1]/td/div', 0)->plaintext);
// get body
$item['tr2'] = trim($article->find('/html/body/table/tbody/tr[2]', 0)->plaintext);
$item['tr3'] = trim($article->find('/html/body/table/tbody/tr[3]', 0)->plaintext);
$item['tr4'] = trim($article->find('/html/body/table/tbody/tr[4]', 0)->plaintext);
$item['tr5'] = trim($article->find('/html/body/table/tbody/tr[5]', 0)->plaintext);

$item['tr11'] = trim($article->find('/html/body/table/tbody/tr[11]', 0)->plaintext);
$item['tr12'] = trim($article->find('/html/body/table/tbody/tr[12]', 0)->plaintext);
$ret[] = $item;
}
// clean up memory
$html->clear();
unset($html);
return $ret;}
}
// -----------------------------------------------------------------------------
// test it!
$ret = scraping();
foreach($ret as $v) {
echo $v['titlu'].'<br>';
echo '<ul>';
echo '<li>'.$v['tr2'].'</li>';
echo '<li>'.$v['tr3'].'</li>';
echo '<li>'.$v['tr4'].'</li>';

echo '<li>'.$v['tr6'].'</li>';

echo '<li>'.$v['tr8'].'</li>';
echo '<li>'.$v['tr9'].'</li>';

Because in foreach you use result of finding /html/body/table you should not use full path but ask:
$item['titlu'] = trim($article->find('/tbody/tr[1]/td/div', 0)->plaintext);
$item['tr2'] = trim($article->find('/tbody/tr[2]', 0)->plaintext);
and so on...
To your curl works, you need move
$ch = curl_init();
before first curl_setopt
