Question

如下所示，每个Object行都有price和name个属性。我想在每一行中再添加一个属性category。所以，这里有一个棘手的问题：我怎么能这样做？

stdClass Object
(
    [0] => stdClass Object
        (
            [price] => 12.99
            [name] => Million Dollar Baby (Two-Disc Widescreen)
        )

    [1] => stdClass Object
        (
            [price] => 599.95
            [name] => Screets Kiddiebank Experience
        )

    [2] => stdClass Object
        (
            [price] => 1999.00
            [name] => Screets Kiddiebank Unlimited
        )

)

Answer 1

这是你在找什么？

<?php
$p1 = new stdClass();
$p1->price = 12.99;
$p1->name = "Million Dollar Baby (Two-Disc Widescreen)";

$p2 = new stdClass();
$p2->price = 599.95;
$p2->name = "Screets Kiddiebank Experience";

$p3 = new stdClass();
$p3->price = 1999.00;
$p3->name = "Screets Kiddiebank Unlimited";

$products = array($p1, $p2, $p3);
foreach($products as $product) {
    $product->category = "Some category";
}

var_dump($products);
?>

Answer 2

你的意思是这样吗？

$objects->{0}->category = 'foo';
$objects->{1}->category = 'bar';
$objects->{2}->category = 'foo';

在对象中包含新项（PHP）
