在下载栏目，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：
读取数据：
foreach ($db->application() as $application) { // get all applications
echo "$application[title]"; // print application title
}
echo "$application[title]"; // print application title
}
条件查询：
$applications = $db->application()
->select("id,title")
->where("web LIKE ?","http://%")
->order("title")
->limit(10)
;
foreach ($applications as $id => $application) {
echo "$application[title]";
}
->select("id,title")
->where("web LIKE ?","http://%")
->order("title")
->limit(10)
;
foreach ($applications as $id => $application) {
echo "$application[title]";
}
读取结果：
$application = $db->application[1]; // get by primary key
$application = $db->application("title = ?","Adminer")->fetch();
$application = $db->application("title = ?","Adminer")->fetch();
处理表关联：
echo $application->author["name"] . ""; // get name of the application author
foreach ($application->application_tag() as $application_tag) { // get all tags of $application
echo $application_tag->tag["name"] . ""; // print the tag name
}
foreach ($application->application_tag() as $application_tag) { // get all tags of $application
echo $application_tag->tag["name"] . ""; // print the tag name
}
JOIN联合查询：
// get all applications ordered by author's name
foreach ($db->application()->order("author.name") as $application) {
echo $application->author["name"] . ": $application[title]";
}
foreach ($db->application()->order("author.name") as $application) {
echo $application->author["name"] . ": $application[title]";
}
结果集分组：
echo $db->application()->max("id"); // get maximum ID
foreach ($db->application() as $application) {
// get count of each application's tags
echo $application->application_tag()->count("*") . "";
}
foreach ($db->application() as $application) {
// get count of each application's tags
echo $application->application_tag()->count("*") . "";
}
完整实例：
<?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]"; // print application title
echo $application->author["name"] . ""; // print name of the application author
foreach ($application->application_tag() as $application_tag) { // get all tags of $application
echo $application_tag->tag["name"] . ""; // print the tag name
}
}
?>
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]"; // print application title
echo $application->author["name"] . ""; // print name of the application author
foreach ($application->application_tag() as $application_tag) { // get all tags of $application
echo $application_tag->tag["name"] . ""; // print the tag name
}
}
?>
