<?php
try
{
//open the database
$db = new PDO("sqlite:/var/www/databases/dog.sqlite");

//create the database
$db->exec("CREATE TABLE Dogs (Id INTEGER PRIMARY KEY, Breed TEXT, Name TEXT, Age INTEGER)");

//insert some data...
$db->exec("INSERT INTO Dogs (Breed, Name, Age) VALUES ('Labrador', 'Tank', 2);".
"INSERT INTO Dogs (Breed, Name, Age) VALUES ('Husky', 'Glacier', 7); " .
"INSERT INTO Dogs (Breed, Name, Age) VALUES ('Golden-Doodle', 'Ellie', 4);");

//now output the data to a simple html table...
print "<table border=1>";
print "<tr><td>Id</td><td>Breed</td><td>Name</td><td>Age</td></tr>";
$result = $db->query('SELECT * FROM Dogs');
foreach($result as $row)
{
print "<tr><td>".$row['Id']."</td>";
print "<td>".$row['Breed']."</td>";
print "<td>".$row['Name']."</td>";
print "<td>".$row['Age']."</td></tr>";
}
print "</table>";

// close the database connection
$db = NULL;
}
catch(PDOException $e)
{
print 'Exception : '.$e->getMessage();
}

This is the function of php-gd to generate a graph.I have test the code and it run successfully.
