Question

I want to get the data in the mysql database and output them in each case as in the database. But when I display them, just see the word "Vi tri cua nguoi dung: Array" without seeing the data. i test by use JSON, I get the result on the screen is:

"[{" Kinhdo ":" 106.71246126888674 "," Vido ":" 10.78865449101134 "}]" 

Can you help me?

<?php
mysql_connect("xxxx","xxx","xxx");
mysql_select_db("a4602996_lv"); 
$query_insert="select Kinhdo,Vido from VietMap where id = (select max(id) from VietMap)";
$sql = mysql_query($query_insert);
    if(mysql_num_rows($sql)){
        while($row=mysql_fetch_assoc($sql)){
        $json[] = $row;
    }
}
//print(json_encode($json).'<br/>');
print 'Vi tri cua nguoi dung: '.$json['Kinhdo'];
mysql_close();
?>

Answer 1

use this :

if(mysql_num_rows($sql))
{
  echo "<pre />";
  while($row=mysql_fetch_assoc($sql))
  {
    print_r($row);
    $json[] = $row;
  }
  echo "</pre>";
}

and you shold provide offset to $json array like :

$json[0]['Kinhdo'];    //for 1st record
