If a SoapServer-Object is instantiated with the option SOAP_SINGLE_ELEMENT_ARRAYS (to automatically get an array if defined in the wsdl) together with SOAP_USE_XSI_ARRAY_TYPE (to allow array types instead of wsdl types), an request sent with an SOAPEnc:Array will be transformed to an array with a "deepness" of 2.

Reproduce code:
class SoapHandler {
	function getSomething($arguments) {

 * SoapServer

$server = new SoapServer($wsdl,
		'uri' => $uri,

 * request

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="">
			<arguments xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="xsd:string[2]">
				<item xsi:type="xsd:string">String 1</item>
				<item xsi:type="xsd:string">String 2</item>

Expected result:
    [0] => String 1
    [1] => String 2

Actual result:
    [0] => Array
            [0] => String 1
            [1] => String 2

It's still not working in 5.2.10-dev as of today. I tested it with the windows binary build from yesterday.

I provided you a test-package, you can download it here:

Checked again against PHP 5.3.2, the issue is still unsolved.

I created two php tests for this. One for wsdl-mode on (works as expected) and one for wsdl-mode off (erroneous as described here)

You can download them here:

Please do me a favor and take care of this issue. If I had enough knowledge, I'd try to submit a patch, but obviously I don't ...

Since the problem exists in the 5.2 as well as in the 5.3 branch, I changed the affected PHP Version

Not sure, if this is the right way to let this issue pop up, but the problem is still not solved. 

Will this be fixed any time soon?

I can confirm the reported behavior with PHP-7.4.  And while I
agree that this doesn't look right, I'm afraid that changing this
long standing behavior might cause more harm than good.  Maybe the
best course of action is to document that.
