php NotORM（PHP的ORM框架）示例代码

NotORM 是一个 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。

连接数据库

1. include "NotORM.php";
2. $pdo = new PDO("mysql:dbname=software");
3. $db = new NotORM($pdo);

复制代码

读取数据

1. foreach ($db->application() as $application) { // get all applications
2. echo "$application[title]\n"; // print application title
3. }

复制代码

条件查询

1. $applications = $db->application()
2. ->select("id, title")
3. ->where("web LIKE ?", "http://%")
4. ->order("title")
5. ->limit(10)
6. ;
7. foreach ($applications as $id => $application) {
8. echo "$application[title]\n";
9. }

复制代码

读取结果

1. $application = $db->application[1]; // get by primary key
2. $application = $db->application("title = ?", "Adminer")->fetch();

复制代码

处理表关联

1. echo $application->author["name"] . "\n"; // get name of the application author
2. foreach ($application->application_tag() as $application_tag) { // get all tags of $application
3. echo $application_tag->tag["name"] . "\n"; // print the tag name
4. }

复制代码

JOIN联合查询

1. // get all applications ordered by author's name
2. foreach ($db->application()->order("author.name") as $application) {
3. echo $application->author["name"] . ": $application[title]\n";
4. }

复制代码

结果集分组

1. echo $db->application()->max("id"); // get maximum ID
2. foreach ($db->application() as $application) {
3. // get count of each application's tags
4. echo $application->application_tag()->count("*") . "\n";
5. }

复制代码

完整例子

1. include "NotORM.php";
2. $connection = new PDO("mysql:dbname=software");
3. $software = new NotORM($connection);
5. foreach ($software->application()->order("title") as $application) { // get all applications ordered by title
6. echo "$application[title]\n"; // print application title
7. echo $application->author["name"] . "\n"; // print name of the application author
8. foreach ($application->application_tag() as $application_tag) { // get all tags of $application
9. echo $application_tag->tag["name"] . "\n"; // print the tag name
10. }
11. }
12. ?>
