php - Handle errors in simple html dom -

i have code public available data fetching website

//array of params  foreach($params $par){  $html = file_get_html('website.com/$par');  $name = $html->find('div[class=name]'); $link = $html->find('div[class=secondname]');  foreach($link $i => $result2) {  $var = $name[$i]->plaintext; echo $result2->href,"<br>"; //insert database }  } 

so goes given website different parameter in url each time on loop, keep getting errors breaks script when 404 comes or server temporarily unavailable. have tried code check headers , check if $html object first still errors, there way can skip errors , leave them out , carry on script?

code have tried checked headers

function url_exists($url){ if ((strpos($url, "http")) === false) $url = "http://" . $url; $headers = @get_headers($url); //print_r($headers); if (is_array($headers)){ //check http error here....should add checks other errors too... if(strpos($headers[0], '404 not found'))     return false; else     return true;     }          else return false; } 

code have tried check if object

if (method_exists($html,"find")) {  // check if html element exists avoid trying parse non-html  if ($html->find('html')) {       // , start searching (and manipulating) dom  

you need more specific, kind of errors getting? line errors out?

edit: since did specify errors you're getting, here's do:

i've noticed you're using single quotes string contains variables. won't work, use double quotes instead, i.e.:

$html = file_get_html("website.com/$par"); 

perhaps issue?

also, use file_get_contents()

if (file_get_contents("website.com/$par") !== false) {   ... }
