查詢

<?php 
$dsn = "mysql:dbname=redmine_default"; 
$username = "root"; 
$password = ""; 

try { 
$conn = new PDO($dsn, $username, $password); 
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
} catch (PDOException $e) { 
    echo "Error: " . $e->getMessage(); 
} 

function mostrarProyectos($conn) { 
    $sql = 'SELECT * FROM projects'; 
    foreach ($conn->query($sql) as $row) { 
     print $row['name'] . "\t"; 
     print $row['id'] . "\t"; 
     print $row['description'] . "\n"; 
    } 
}  


//creating a table with 4 columns 
?> 
<table border="1" cellspacing=1 cellpadding=2 style="font-size: 8pt"><tr> 
<td><font face="verdana"><b>ID</b></font></td> 
<td><font face="verdana"><b>Name</b></font></td> 
<td><font face="verdana"><b>Status</b></font></td> 
<td><font face="verdana"><b>Desc</b></font></td> 
</tr> 

<?php 
//here comes the SQL query 
    $query = "SELECT name, description FROM projects where status > 1"; 
    $resultado = $conn->query($query); 
    $numero = 0; 
    foreach($resultado as $row) 
    { 
    echo "<tr><td width=\"25%\"><font face=\"verdana\">" . 
    $row["id"] . "</font></td>"; 
    echo "<td width=\"25%\"><font face=\"verdana\">" . 
    $row["name"] . "</font></td>"; 
    echo "<td width=\"25%\"><font face=\"verdana\">" . 
    $row["status"] . "</font></td>"; 
    echo "<td width=\"25%\"><font face=\"verdana\">" . 
    $row["description"]. "</font></td></tr>"; 

    $numero++; 
    } 
    echo "<tr><td colspan=\"15\"><font face=\"verdana\"><b>N&uacutemero: " . $numero . 
    "</b></font></td></tr>"; 

    mysql_free_result($result); 
    mysql_close($link); 
?> 
</table 
    </body>
