Answer 1

find() is a member function of
http://simplehtmldom.sourceforge.net/
You have commented out the line
$html = file_get_html('http://testwork.ru/Tempp/domains.php');
With CURL it will return html content not the parsed data.
If you are intend to use CURL then use
$html_data = curl_exec($ch);
curl_close ($ch);
$html = str_get_html($html_data ); // using the returned html from curl to the parser
Then do the rest of the parsing part.

Answer 2

You need to edit the code like this:
// Find all tr
$row = 0;
if(!$html) { // check if $html does exists
foreach($html->find('tr') as $tr){
if($row!=0){
$row++;
$column = 0;
foreach($tr->find('td') as $td){
$column++;
$text = $td->plaintext;
$ArrTd[$column] = $text;
}
}
if(iconv_strlen($ArrTd[0]) > $SymbolsCountMin && iconv_strlen($ArrTd[0]) < $SymbolsCountMax && !in_array($ArrTd[0], $SymbolsBackList)){
$ArrTr[$row] = $ArrTd;
}
}
}
or use a try and catch statement
