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

提供された WSDL、PHP classmap、ResLFAType 定義、および resLFAsucces 要素をちょうど 1 つ含むレスポンスを使って失敗を再現します。unbounded 要素に対する ext-soap のデシリアライズ経路を追跡し、singleton の処理を複数要素の場合と比較します。1 つのレスポンスで代入例外を発生させずに型付き配列が設定され、このケースをカバーする回帰テストがあれば完了です。
