PHP preg_match_all in option value without disabled options

Question

Any suggestion how to do the result value option without disabled option with php preg_match_all?

<option value="1" disabled="disabled"> google</option>
<option value="2" selected="selected">- yahoo</option>
<option value="3">- youtube</option>
<option value="4">- facebook</option>
<option value="5" disabled="disabled"> twitter</option>
<option value="6">- tumblr</option>
<option value="7">- bing</option>

how to echo just value without disabled options maybe with preg_match_all?

i have some code but not work,

   $string = array(
   '/<option value=\"(.*)\" selected=\"selected\">-/sU',
   '/<option value=\"(.*)\">-/U',);

$option = curl_exec($ch);
foreach ($string as $key) {
 if (preg_match_all($key, $option, $matches)) {
  $count = count($matches[1]);
    for ($i=0; $i < $count ; $i++) { 
     echo $matches[1][$i]."\n";
  }
 }else {
   echo "match NOT found";
 }
}

i want to the result like this,

value = 2,3,4,6,7

thanks for helping,

You could go the other way around. You know the options, put them in an array, grab the disabled ones and subtract them from the array with options. — RST, Apr 17 '16 at 11:41

You should use XPath. If you want I can show you how it works. — Boy, Apr 17 '16 at 11:45

Using XPath is easy, check the following solution:

$doc = new DOMDocument();
$doc->loadHTML('<option value="1" disabled="disabled"> google</option><option value="2" selected="selected">- yahoo</option><option value="3">- youtube</option><option value="4">- facebook</option><option value="5" disabled="disabled"> twitter</option><option value="6">- tumblr</option><option value="7">- bing</option>');

$xpath = new DOMXPath($doc);
$notDisabledOptions = $xpath->query("//option[not(@disabled)]");
$numberOfOptions = $notDisabledOptions->length;

for($i = 0; $i < $numberOfOptions; $i++){
      echo $notDisabledOptions->item($i)->attributes->getNamedItem("value")->nodeValue;
}

For more info on how to use XPath, check this XPath tutorial.

Well, you can set the option values in the array. And then manipulate that array according to your likings.
