Using php to populate html table -


i need populate table data regarding 10 countries using .php , .html file. have downloaded xampp (7.1.8) working on macbook pro 2012 running sierra (can not xampp-vm run - signal killed error message on start up).

i have created database testdb in mysql , coded database.html file , getuser.php file below , saved them htdocs folder on server - when renders, isn't picking xml file or data within.

i believe problem either on line 46 in php or line 36 in html, don't know enough php to know how change make work. appreciated,

thanks

database.html

<head>      <script>          function showuser (str) {             if (str=="") {                 document.getelementbyid("txthint").innerhtml="";                  return;             }              if (window.xmlhttprequest)  {                  // code ie7+, firefox, chrome, opera, safari                  xmlhttp=new xmlhttprequest ();              } else { // code ie6, ie5                  xmlhttp=new activexobject ("microsoft.xmlhttp");              }              xmlhttp.onreadystatechange=function () {                  if (this.readystate==4 && this.status==200) {                      document.getelementbyid("hint").innerhtml=this.responsetext;                 }             }              xmlhttp.open("get","getuser.php?q="+str,true);             xmlhttp.send();         }      </script>  </head>  <body>      <form>      <select name="users" onchange="showuser(this.value)">          <option value ="">select country:</option>          <option value ="1">united kingdom</option>          <option value="2">france</option>          <option value="3">germany</option>          <option value="4">india</option>          <option value="5">hungary</option>          <option value="6">ireland</option>          <option value="7">greece</option>          <option value="8">usa</option>          <option value="9">japan</option>          <option value="10">spain</option>          </select>      </form>  <br>      <div id="hint"><b>country info highlighted below</b></div>  </body>

getuser.php 

<style>      table {          width: 100%;          border-collapse: collapse;     }      table, td, th {          border: 1px solid black;          padding 5px;      }      th {text-align: left;}  </style>  </head> 

<?php  $q = intval ($_get['q']);   $con = mysqli_connect('localhost', 'root', '');  if (!$con) {      die('could not connect: ' . mysqli_error($con)); }  mysqli_select_db($con,"testdb");  $sql = "select * records id = '".$q."'";  $result = mysqli_query($con,$sql);   echo "<table  <tr>  <th>country</th>  <th>capital city</th>  <th>currency</th>  </tr>";  error_reporting(e_error | e_parse);  while ($row = mysqli_fetch_array($result)) {      echo "<tr>";      echo "<td>" . $row['country'] . "</td>";      echo "<td>" . $row['capital city'] . "</td>";      echo "<td>" . $row['currency'] . "</td>";      echo "</tr>"; }  echo "</table>";  mysqli_close($con);  ?>  </body>

the problem fetch array instead of assoziation. use mysqli_fetch_assoc(). can access array do.

while ($row = mysqli_fetch_assoc($result))

and close first table tag.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
