无法从mysql数据库加载数据

Question

这是我的问题。我正在设置日历，并且无法从sqlite数据库切换到我的mysql数据库。

问题是DayPilot在从mysql传递时没有加载事件。非常感谢任何帮助。谢谢。

<?php 

//$db_exists = file_exists("daypilot1.sqlite"); 
//$db = new PDO('sqlite:daypilot.sqlite'); This works 

// i tried these two ways. both of them did not work. 

$db = new PDO("mysql:host=localhost;dbname=his", "root", "123"); 


/* $servername = "localhost"; 
$username = "root"; 
$password = "123"; 


try { 
    $db = new PDO("mysql:host=$servername;dbname=his", $username, $password); 
    echo "Connected successfully"; 
    } 
catch(PDOException $e) 
    { 
    echo $e->getMessage(); 
    } 
    */ 

if (!$db) { 
    //create the database 
    $db->exec("CREATE TABLE IF NOT EXISTS events (
         id INTEGER PRIMARY KEY, 
         name TEXT, 
         start DATETIME, 
         end DATETIME, 
         resource VARCHAR(30))"); 

    $messages = array(
        array('name' => 'Event 1', 
         'start' => '2013-05-09T00:00:00', 
         'end' => '2013-05-09T10:00:00', 
         'resource' => 'B') 
       ); 

    $insert = "INSERT INTO events (name, start, end, resource) VALUES (:name, :start, :end, :resource)"; 
    $stmt = $db->prepare($insert); 

    $stmt->bindParam(':name', $name); 
    $stmt->bindParam(':start', $start); 
    $stmt->bindParam(':end', $end); 
    $stmt->bindParam(':resource', $resource); 

    foreach ($messages as $m) { 
     $name = $m['name']; 
     $start = $m['start']; 
     $end = $m['end']; 
     $resource = $m['resource']; 
     $stmt->execute(); 
    } 

}

试试这个

<?php 

//$db_exists = file_exists("daypilot1.sqlite"); 
//$db = new PDO('sqlite:daypilot.sqlite'); This works 

// i tried these two ways. both of them did not work. 

$db = new PDO("mysql:host=localhost;dbname=his", "root", "123"); 


/* $servername = "localhost"; 
$username = "root"; 
$password = "123"; 


try { 
    $db = new PDO("mysql:host=$servername;dbname=his", $username, $password); 
    echo "Connected successfully"; 
    } 
catch(PDOException $e) 
    { 
    echo $e->getMessage(); 
    } 
    */ 

if (!$db) { 
    //create the database 
    $db->exec("CREATE TABLE IF NOT EXISTS events (
         id INTEGER PRIMARY KEY, 
         name TEXT, 
         start DATETIME, 
         end DATETIME, 
         resource VARCHAR(30))"); 

    $messages = array(
        array('name' => 'Event 1', 
         'start' => '2013-05-09T00:00:00', 
         'end' => '2013-05-09T10:00:00', 
         'resource' => 'B') 
       ); 

    $insert = "INSERT INTO events (name, start, end, resource) VALUES (:name, :start, :end, :resource)"; 
    $stmt = $db->prepare($insert); 


    foreach ($messages as $m) { 
     $name = $m['name']; 
     $start = $m['start']; 
     $end = $m['end']; 
     $resource = $m['resource']; 
    } 

    $stmt->bindParam(':name', $name); 
    $stmt->bindParam(':start', $start); 
    $stmt->bindParam(':end', $end); 
    $stmt->bindParam(':resource', $resource); 
    $stmt->execute(); 

}

我没有测试过，但希望它会解决你的问题。
