class BlastAPI{

    public function blastdata(){

    $url = "https://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Put&QUERY=SSWWAHVEMGPPDPILGVTEAYKRDTNSKK&PROGRAM=blastp&FILTER=L&DATABASE=nr&FORMAT_TYPE=XML";
        $ncontent = $this->rid($url);
        echo '
RID :'.$ncontent.'
';
        $geturl = $this->geturl($ncontent);
        echo $geturl;
        $fulldata = $this->getfullData($geturl);
        if($fulldata != ''){
        echo '
';
        var_dump($fulldata);
        echo '
';
    }else{
        echo "Code Once";
    }
    }

    public function rid($url){

        $surl = $url;
        echo $surl;
    //header('Content-type: text/html');
        $content = file_get_contents($surl);    
        $doc = new DOMDocument();
        libxml_use_internal_errors(true);
        $doc->loadHtml($content);
    libxml_use_internal_errors(false);

        $data = $doc->getElementById("rid");
        $rid = $data->getAttribute('value');

        return $rid;
    }
    public function geturl($rid){
        $srid = $rid;
        $mainurl = "https://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Get&RID=$srid&FORMAT_OBJECT=SearchInfo";
        return $mainurl;
    }
    public function getfullData($url){
        $murl = $url;
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $murl);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
        $str = curl_exec($curl);
        curl_close($curl);  
        return $str;
    }
}
$nblast = new BlastAPI();
$nblast->blastdata();
