php - Finding the value of an option with specific string -

consider snippet select form:

    <select name="cat_id"">         <option  value="33">apple</option>         <option  value="44">banana</option>         <option  value="48">carrot</option>         <option  value="50">dew</option>         <option  value="77">eggplant</option>         <option  value="84">fern</option>         <option  value="92">grass</option>     </select> 

is there way, using simple dom, can extract value="x" specific string.

example, want value of dew, hence, must able 50 tried searching , playing, cannot find exact answer:

parsing drop down menu php simple dom <-- values doesn't start 0 nor increments uniformly

php , simple_html_dom.php, selected option <-- not have selected entry in select form

i need value specific string can use send form using curl.

hope, can help. in advance , more power.

the following code parse option nodes , when searched text matched, display corresponding value , ends:

$input =  <<<_data_     <select name="cat_id">         <option  value="33">apple</option>         <option  value="44">banana</option>         <option  value="48">carrot</option>         <option  value="50">dew</option>         <option  value="77">eggplant</option>         <option  value="84">fern</option>         <option  value="92">grass</option>     </select> _data_;  // create dom object $html = new simple_html_dom(); // load html string $html->load($input);  // searched text $searchtext = 'dew';  // create regex pattern (match $searchtext followed or preceded number of spaces/tabs/newlines ...) // flag stands case insensitive match $pattern = '/\s*'.$searchtext.'\s*/i';   foreach( $html->find('select[name="cat_id"] option') $option ){     echo $string = $option->plaintext;      // check if current node contains searched text     if( preg_match($pattern, $string) ){         $value = $option->value;          echo ' => ' . $value;          // exit loop when done         break;     }      echo '<br>'; } 

output
