php - Change my array dynamically -


i have function returns array this:

[ "var0 =>    300  pr. d. joÃo", "var1 =>a passar", "var2 =>", "var3 =>    904  q.bela vista", "var4 =>a passar", "var5 =>", "var6 =>    905  monte virgem", "var7 =>a passar", "var8 =>", "var9 =>    300  telheira - c", "var10 =>a passar", "var11 =>", "var12 =>   200  cast. queijo", "var13 =>20:39", "var14 =>5min"  ]

and need result next example: it's necessary in format.

[ "route" =>  "300  pr. d. joÃo", "eta" =>"a passar", "waittime" =>"", "route" =>  "904  q.bela vista", "eta" =>"a passar", "waittime" =>"", "route" =>" 905  monte virgem", "eta" =>"a passar", "waittime" =>"", "route" =>" 300  telheira - c", "eta" =>"a passar", "waittime" =>"", "route" =>" 200  cast. queijo", "eta" =>"20:39", "waittime" =>"5min" ]

and webservice php code is:

function getpage ($codigo) {     $link = "http://www.stcp.pt/pt//itinerarium/soapclient.php?codigo=";     $dom = new domdocument();     $homepage = file_get_contents($link.$codigo);     $dom->loadhtml($homepage);     $tables = $dom->getelementsbytagname('table');     $table = $tables->item(0);     $i = 0;     $var = array();     foreach ($table->childnodes $tr) {       if ($tr->nodename == 'tr') {         foreach ($tr->childnodes $td) {             $i++;             $tds= $td->nodevalue;             if ($i%2 == 0) {             } else {                 array_push($var, $tds);                              }         }       } else {         echo "string ";       }     }     $first = array_shift($var);                  $second = array_shift($var);                     $third = array_shift($var);     $maxvar = sizeof($var);     $final_array = array();     ($k=0; $k < sizeof($var); $k++) {          ${'var' . $k} = $var[$k];         array_push($final_array, "var$k =>".$var[$k]);     }     echo json_encode($final_array); }

how can return json example show?

because associative arrays must have unique keys, cannot have route, eta, or waittime appearing more once in output. can create nested array represents data quite nicely.

$a = [ "var0 =>    300  pr. d. joÃo", "var1 =>a passar", "var2 =>", "var3 =>    904  q.bela vista", "var4 =>a passar", "var5 =>", "var6 =>    905  monte virgem", "var7 =>a passar", "var8 =>", "var9 =>    300  telheira - c", "var10 =>a passar", "var11 =>", "var12 =>   200  cast. queijo", "var13 =>20:39", "var14 =>5min" ];  function removevarprefix($x) {     return preg_replace('/^var\d+\s*=>\s*/', '', $x); }  $b = array_map(function($set) {     list($route, $eta, $waittime) = array_map('removevarprefix', $set);     return ['route'=>$route, 'eta'=>$eta, 'waittime'=>$waittime]; }, array_chunk($a, 3));  echo json_encode($b, json_pretty_print);

output (updated show json)

[     {         "route": "300  pr. d. jo\u00c3o",         "eta": "a passar",         "waittime": ""     },     {         "route": "904  q.bela vista",         "eta": "a passar",         "waittime": ""     },     {         "route": "905  monte virgem",         "eta": "a passar",         "waittime": ""     },     {         "route": "300  telheira - c",         "eta": "a passar",         "waittime": ""     },     {         "route": "200  cast. queijo",         "eta": "20:39",         "waittime": "5min"     } ]

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
