kandi X-RAY | hoya Summary

hoya is a Java library typically used in Devops, Continuous Deployment, Docker, Hadoop applications. hoya has no bugs, it has no vulnerabilities, it has build file available and it has medium support. However hoya has a Non-SPDX License. You can download it from GitHub.
Hoya is a YARN application to deploy existing distributed applications on YARN, monitor them and make them larger or smaller as desired -even while the cluster is running. Hoya has a plug-in provider architecture to support different applications, and currently supports Apache HBase and Apache Accumulo. Clusters can be stopped, "frozen" and restarted, "thawed" later; the distribution of the deployed application across the YARN cluster is persisted -enabling a best-effort placement close to the previous locations on a cluster thaw. Applications which remember the previous placement of data (such as HBase) can exhibit fast start-up times from this feature. YARN itself monitors the health of 'YARN containers" hosting parts of the deployed application -it notifies the Hoya manager application of container failure. Hoya then asks YARN for a new container, into which Hoya deploys a replacement for the failed component. As a result, Hoya can keep the size of managed applications consistent with the specified configuration, even in the face of failures of servers in the cluster -as well as parts of the application itself.

                      QUESTION

                      Removing a key from a nested array in php

                      Asked 2021-Apr-29 at 17:41

                      I am trying to display information taken from a mysql database but i do not want to display the 'id' field in the results. i got the displaying part down just fine. just need to remove a field from the view.

                      $plantarray = array();
                      if($result = $mysqli->query($hoyaquery)){
                          if(mysqli_num_rows($result) > 0){
                              while($row = mysqli_fetch_assoc($result)){
                                  $plantarray[] = $row;
                              }
                          } 
                      }
                      

                      The code will return a nested array of results but it includes the tables id field.

                      its then displayed using:

                      <?php if (count($plantarray) > 0): ?>
                      <table>
                        <thead>
                          <tr>
                            <th><?php echo implode('</th><th>', array_keys(current($plantarray))); ?></th>
                          </tr>
                        </thead>
                        <tbody>
                      <?php foreach ($plantarray as $row): array_map('htmlentities', $row); ?>
                          <tr>
                            <td><?php echo implode('</td><td>', $row); ?></td>
                          </tr>
                      <?php endforeach; ?>
                        </tbody>
                      </table>
                      <?php endif; ?>
                      

                      ive tried to loop through the outside array and target the key 'id' but it doesnt do anything at all if i unset the id.

                      foreach($plantarray as $key){
                        unset($key['id']);
                      }
                      

                      this does nothing at all.

                      i know the problem is in the looping, because if i set an array with the same data and i unset['id'] then it removes the id.

                      $p = [ "id" => 3, "Family" => "Apocynaceae", "Genus" => "Hoya", "Species" => "curt" ];
                      unset($p["id"]);
                      print_r($p);
                      

                      i could have this completely wrong. I'm not sure. I'm unsure where its going wrong.

                      The reason that your loop doesn't work is because you aren't unsetting the values in the array itself, rather in the "copy" that is generated during the foreach loop. If you want to use this solution then the right code looks something like this:

                      foreach($plantarray as &$key){
                        unset($key['id']);
                      }
                      

                      The & symbol will pass the row by reference which will make your manipulations be kept in the original array.

                      That said, this is not a performant way of doing this. Ostensibly, you have a query somewhere above this code that looks something like

                      $hoyaquery = "SELECT * FROM plant-table-name";
                      

                      Instead, just don't get the id column from the database at all.

                      $hoyaquery = "SELECT Family, Genus, Species FROM plant-table-name"
                      

                      That will prevent you from needing to loop through all your results in the first place.
