SOLAR^1.1.2

记录对象继承自Solar_Struct，Solar_Struct又实现了ArrayAccess,、Countable和IteratorAggregate接口。这意味着，你几乎就可以把记录对象当成数组使用。

<?php
// a single blog record, blog.id = 1
$item = $model->blogs->fetch(1);

// print the name and value of each property
foreach ($item as $col => $val) {
    $label = htmlspecialchars($col);
    $value = htmlspecialchars($val);
    echo "$label: $value<br />";
}

// echo the ID as a property or as an array element
echo $item->id . " is the same as " .  $item['id'];

你也可以调用记录地象的任何方法；这可能是在您的域中实现记录级商业逻辑的方法。

和记录对象一样，集合对象也继承自Solar_Struct。这也意味着，你几乎就可以把集合对象当成数组使用。

<?php
// a collection of blog records
$list = $model->blogs->fetchAll();

// print the title of each blog entry.
// note that $n is a sequential array key,
// *not* the primary key value.
foreach ($list as $n => $blog) {
    echo "Primary key ID " . htmlspecialchars($blog->id)
       . " is titled " . htmlspecialchars($blog->title)
       . '<br />';
}

// how many records are in the collection?
$count = count($list);

// using fetchAssoc() will key the collection on the first
// column of the results. in this case, becasue 'id' is the
// first column, the array key and the primary key are the
// same thing.
$list = $model->blogs->fetchAssoc();
foreach ($list as $key => $blog) {
    echo "Primary key ID " . htmlspecialchars($blog->id)
       . " is the same as the assoc key " . htmlspecialchars($key)
       . '<br />';
}

集合对象提供了几个方法让你获取集合的整体信息。
