php - SimpleXML 解析 WoWArmory 属性的问题

Question

这是一个示例项目:

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [displayInfoId] => 62116
            [durability] => 100
            [gem0Id] => 41401
            [gem1Id] => 40123
            [gem2Id] => 0
            [gemIcon0] => inv_jewelcrafting_shadowspirit_02
            [gemIcon1] => inv_jewelcrafting_gem_37
            [icon] => inv_helmet_98
            [id] => 48592
            [level] => 245
            [maxDurability] => 100
            [name] => Liadrin's Headpiece of Triumph
            [permanentEnchantIcon] => ability_warrior_shieldmastery
            [permanentEnchantItemId] => 44876
            [permanentenchant] => 3819
            [pickUp] => PickUpLargeChain
            [putDown] => PutDownLArgeChain
            [randomPropertiesId] => 0
            [rarity] => 4
            [seed] => 0
            [slot] => 0
        )

)

我正在尝试为每个项目获取一个 JSON 对象，但大约有 17 个左右，如果我尝试 json_encode()，它会给我“@attributes”作为包含所有内容的对象我想要的东西。帮忙？

Answer 1

像这样:

<?php
$sxm = new SimpleXMLElement("<a name=\"kkk\" other=\"foo\"/>");
$attrs = $sxm->attributes();
var_dump(json_encode(reset($attrs)));

给出:

string(28) "{"name":"kkk","other":"foo"}"

您遇到的问题是因为 $xmlObj->attributes() 返回一个 SimpleXMLElement，当转换为数组时，它是一个带有键“@”的数组attributes"和一个带有数组的值，该数组实际上具有作为 (name => value) 对的属性。
