NotORM 是一個(gè) PHP 庫(kù)，用來(lái)簡(jiǎn)化和數(shù)據(jù)庫(kù)的交互。最有特色的功能是處理表關(guān)聯(lián)關(guān)系非常簡(jiǎn)單。另外 NotORM 的性能非常的高，設(shè)置高過(guò)內(nèi)置的驅(qū)動(dòng)。

連接數(shù)據(jù)庫(kù)

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

讀取數(shù)據(jù)

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

條件查詢(xún)

$applications = $db->application()
    ->select("id, title")
    ->where("web LIKE ?", "http://%")
    ->order("title")
    ->limit(10)
;
foreach ($applications as $id => $application) {
    echo "$application[title]\n";
}

讀取結(jié)果

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

處理表關(guān)聯(lián)

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聯(lián)合查詢(xún)

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

結(jié)果集分組

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";
}

完整例子

<?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
    }
}
?>
