$cluster   = Cassandra::cluster()                 // connects to localhost by default
                 ->build();

$keyspace  = 'new';
$session   = $cluster->connect($keyspace);        // create session, optionally scoped to a keyspace
$statement = new Cassandra\SimpleStatement(       // also supports prepared and batch statements
    'SELECT * FROM new.country_by_id');

$future    = $session->executeAsync($statement);  // fully asynchronous and easy parallel execution
$result    = $future->get();                      // wait for the result, with an optional timeout

foreach ($result as $row) {                       // results and rows implement Iterator, Countable and ArrayAccess
    print  $row['country_name']."<br />";

  • after this code: `$session = $cluster->connect($keyspace); print "jijijij";` it does not show any data. – Veronica Nov 13 '17 at 07:02
  • PHP is server side and the output created with it is interpreted by a browser, the problem will be with the browser you are using and not the php code I expect. – pokeybit Nov 15 '17 at 12:36
  • Try firefox, then firefox quantum, chrome and even safari. Let us know the results please – pokeybit Nov 15 '17 at 12:37
  • Enable error logging with php `error_reporting(-1);ini_set('display_errors', 'On');` at the top of your code (after `session_start();`) if you have it there. – pokeybit Nov 15 '17 at 12:41
  • i use **error_reporting(-1);ini_set('display_errors', 'On');** at top of my code ,this messege **Fatal error: Uncaught Error: Class 'Cassandra' not found in /var/www/html/test.php:7 Stack trace: #0 {main} thrown in /var/www/html/test.php on line 7** was shown. – Veronica Nov 16 '17 at 05:52
  • without this **error_reporting(-1);ini_set('display_errors', 'On');** browser shows :**localhost is currently unable to handle this request. HTTP ERROR 500** – Veronica Nov 16 '17 at 05:55
  • i used google chrome , restart cassndra and apache2 , i also added **extension:cassandra.so** at etc/php/7.1/apache2/php.ini and etc/php/7.1/cli/php.ini and with php 7.0 **but not worked** – Veronica Nov 16 '17 at 06:31
  • With the error reporting on, it states that Cassandra has not loaded. `/var/www/html/test.php` **localhost is currently unable to handle this request. HTTP ERROR 500** is a mysql error that arises 'after' cassandra had failed to load – pokeybit Nov 16 '17 at 07:49
  • Amend you post with the contents of `test.php` please. Place it in a code block and remember to remove any sensitive information such as passwords or private locations. – pokeybit Nov 16 '17 at 07:51
  • Is line 7: `$future = $session->executeAsync($statement);` ? – pokeybit Nov 16 '17 at 07:53
  • how can i load cassandra in my code?i dont know that????????? – Veronica Nov 16 '17 at 09:49
  • `//require_once 'Cassandra.php';` remove the `//` – pokeybit Nov 16 '17 at 10:44
  • how can i know cassandra class address. i used usr/share/php/docs/cassandra/doc/cassandra.php but it can not works , with this messege **"Warning: require_once(usr/share/php/docs/cassandra/doc/cassandra.php): failed to open stream: No such file or directory in /var/www/html/test.php on line 8"** – Veronica Nov 18 '17 at 10:21
  • You will need to find out where it is located and use the correct path with `require_once` – pokeybit Nov 18 '17 at 13:51
  • thank you for you'r help but i dont know what to do yet.in fact i search in google but i dont find any thing of that which library should included. – Veronica Nov 20 '17 at 07:00
