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

it seems its the SOAP_SINGLE_ELEMENT_ARRAYS feature, seems i have overlook it?

I'm surprised that the lib isn't doing that on its own

If I had to take a guess, this option was added as an opt-in option to preserve BC.
It wasn't here from the start and was added to fix a bug: 7dc9be7
