ext-soap + unbounded elements + classmap + 1 element

Description

The WSDL for this class:

<xsd:complexType name="resLFAType">
    <xsd:sequence>
        <xsd:element name="resInfo"	type="tns:resInfoType"></xsd:element>
        <xsd:element name="resLFAsucces" type="tns:LFAsuccesType" minOccurs="0" maxOccurs="unbounded"></xsd:element>
        <xsd:element name="resLFAerror" type="tns:LFAerrorType" minOccurs="0" maxOccurs="unbounded"></xsd:element>
    </xsd:sequence>
</xsd:complexType>
    

while using this SOAP classmap:

    protected static array $classMap = [
        'resInfoType' => ResInfoType::class,

        'resLFAType' => ResLFAType::class,

        'LFAsuccesType' => LFASuccessType::class,
        'LFAerrorType' => LFAErrorType::class,
    ];

while having this for ResLFAType:

<?php

class ResLFAType
{
    public ?ResInfoType $resInfo;

    /**
     * @var LFASuccessType[]
     */
    public array $resLFAsucces = [];
    /**
     * @var LFAErrorType[]
     */
    public array $resLFAerror = [];
}

When the SOAP service is responding with multiple resLFAsucces and/or resLFAerror, everything works fine

BUT when the SOAP service is responding with exactly one of resLFAsucces, then i get this Exception:

Cannot assign LFASuccessType to property ResLFAType::$resLFAsucces of type array

it seems to understand when getting multiple entries to assign them correctly to the property,
but it fails when only getting one object.

PHP Version

PHP 8.2.6

Operating System

No response

使用提供的 WSDL、PHP classmap、ResLFAType 定义以及包含恰好一个 resLFAsucces 元素的响应重现该失败。跟踪 ext-soap 对 unbounded 元素的反序列化路径，并比较 singleton 与多个元素时的处理方式。完成标准是：单个响应能够填充类型化数组而不会出现赋值异常，并且有一个回归测试覆盖此情况。
