php - How to create array using javascript with a database mysql? -


anyone can me problem thank in advance google chart need change task , hours per day dynamically, need database can connect database , put them on array how can that.

 <html>       <head>         <script type="text/javascript" src="https://www.google.com/jsapi"></script>         <script type="text/javascript">           google.load("visualization", "1", {packages:["corechart"]});           google.setonloadcallback(drawchart);           function drawchart() {             var data = google.visualization.arraytodatatable([               ['task', 'hours per day'],               ['work',     11],               ['eat',      2],               ['commute',  2],               ['watch tv', 2],               ['sleep',    7]             ]);              var options = {               title: 'my daily activities'             };              var chart = new google.visualization.piechart(document.getelementbyid('chart_div'));             chart.draw(data, options);           }         </script>       </head>       <body>         <div id="chart_div" style="width: 900px; height: 500px;"></div>       </body>     </html>

first need design database structure. example:

** activities **  | id |   task   | hours  |  | 1  |   work   |   11   | | 2  |   eat    |   2    | | 3  | cummute  |   2    | | 4  | watch tv |   2    |  | 5  |  sleep   |   7    |

now need make database connection. ( easiest way, there better ways this, example )

<?php  $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');  if (!$link) {      die('not connected : ' . mysql_error());  }    // make foo current db  $db_selected = mysql_select_db('your_db_name', $link);  if (!$db_selected) {      die ('can\'t use database : ' . mysql_error());  } ?>

you need build code dynamic:

   var data = google.visualization.arraytodatatable([       ['task', 'hours per day'],       ['work',     11],       ['eat',      2],       ['commute',  2],       ['watch tv', 2],       ['sleep',    7]     ]);

in example, title static

   var data = google.visualization.arraytodatatable([       ['task', 'hours per day'],       <?php          $query = mysql_query("select * activities");          $count = mysql_row_count($query);          $i = 0;          $last = ',';          while ($row = mysql_fetch_array($result)) {           $i++;           if($i == $count) { $last = ''; )           echo "['". $row['task'] .", ". $row['hours'] ." '] " . $last          }        ?>     ]);
