HTTP(200) verification in PHP

Asked

I did my checking so, only in mine gave an error and in other verification systems did not give. I wonder where it was that I went wrong?

 $host = 'IP do HOST';
 $conectado = @fsockopen($host, 80);

 if (is_resource($conectado)) {
    print 'online';
 }else{
    print 'offline';
 }

Below my system and another system checked.

Meu sistema

Sistema verificado

php http-request

  • You are using curl_init ? Or you know if your page is returning the status 200?

  • 'Cause it’s I tried to make via CURL plus my trial hosting doesn’t allow I guess.

  • I want to send a command to a page to return the value 200.

  • Utilize curl_getinfo

  • Neither curl_getinfo(); as tbm does not appear phpinfo();

  • error 404 on page.

  • Have you tried to verify the answer with the stream_get_meta_data ?

  • How do I do that?

  • If possible [Edit] your question and add how you are doing. It becomes easier to show a solution.

  • So I changed, I tried to be as clear as I could.

  • In my system only returned at 14:40 on the other verification system nor crashed.

To use the fsockopen, you need to remove the schema (http://) and the bar at the end.

Example:

$host = 'pt.stackoverflow.com';
$conectado = fsockopen($host, 80);

if (is_resource($conectado)) {
    print 'online';
}else{
    print 'offline';
}

Alternatives

Beyond the fsockpopen, you can also use fopen and curl.

Example with fopen:

$host = '/';
$conectado = fopen($host, 'r');

@$result = @stream_get_meta_data($conectado);

if (is_resource($conectado) && strpos($result['wrapper_data'][0], "200") !== false) {
    print 'online';
}else{
    print 'offline';
}

Example with curl:

$host = 'http://answall.com:80';

ob_start();
$ch = curl_init($host);
curl_exec($ch);
$info = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
ob_end_clean();

if( $info === 200 ) {
    echo "Offline";
} else {
    echo "Offline";
}

  • I was wrong, I will change the question. Pq on my system has no "/". And with fopen and Curl does not work on my test system.

  • I got it, I was really missing something in my code yours made me see. Thank you all for your help
