NotORM（PHP的ORM框架）示例代码

在烈火下载栏目，我们发布了NotORM，这是一个完全免费的 PHP 库，用来简化和数据库的交互。最有特色的功能是处理表关联关系非常简单。另外 NotORM 的性能非常的高，设置高过内置的驱动。

下边来看一些NotORM的示例代码：

连接数据库：

Copy to Clipboard引用的内容：[www.veryhuo.com] include "NotORM.php";
$pdo = new PDO("mysql:dbname=software");
$db = new NotORM($pdo);

读取数据：

Copy to Clipboard引用的内容：[www.veryhuo.com] foreach ($db->application() as $application) { // get all applications
echo "$application[title]\n"; // print application title
}

条件查询：

Copy to Clipboard引用的内容：[www.veryhuo.com] $applications = $db->application()
->select("id, title")
->where("web LIKE ?", "http://%")
->order("title")
->limit(10)
;
foreach ($applications as $id => $application) {
echo "$application[title]\n";
}

读取结果：

Copy to Clipboard引用的内容：[www.veryhuo.com] $application = $db->application[1]; // get by primary key
$application = $db->application("title = ?", "Adminer")->fetch();

处理表关联：

Copy to Clipboard引用的内容：[www.veryhuo.com] echo $application->author["name"] . "\n"; // get name of the application author
foreach ($application->application_tag() as $application_tag) { // get all tags of $application
echo $application_tag->tag["name"] . "\n"; // print the tag name
}

JOIN联合查询：

Copy to Clipboard引用的内容：[www.veryhuo.com] // get all applications ordered by author's name
foreach ($db->application()->order("author.name") as $application) {
echo $application->author["name"] . ": $application[title]\n";
}

结果集分组：

Copy to Clipboard引用的内容：[www.veryhuo.com] echo $db->application()->max("id"); // get maximum ID
foreach ($db->application() as $application) {
// get count of each application's tags
echo $application->application_tag()->count("*") . "\n";
}

完整实例：

Copy to Clipboard引用的内容：[www.veryhuo.com] <?php
include "NotORM.php";
$connection = new PDO("mysql:dbname=software");
$software = new NotORM($connection);

foreach ($software->application()->order("title") as $application) { // get all applications ordered by title
echo "$application[title]\n"; // print application title
echo $application->author["name"] . "\n"; // print name of the application author
foreach ($application->application_tag() as $application_tag) { // get all tags of $application
echo $application_tag->tag["name"] . "\n"; // print the tag name
}
}
?>
