I made small error in my test script, the correct code is:
public function getSoapData()
{
$soapData = array();
$this->buildElement($soapData, array('element1', 'element2',
'element3', 'element4', 'foo'));
$soapData['element1']['element2']['element3']['element4']['foo']
= 'bar';
return $soapData;
}

Description:
------------
On of our suppliers expects heavily nested XML in the request we make.
Constructions like the following are not uncommon in the requests we have to make to them:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Body>
<element1>
<element2>
<element3>
<element4>
<foo>bar</foo>
</element4>
</element3>
</element2>
</element1>
</SOAP-ENV:Body>
In order to create these nested structures, we used a helper as mentioned in the test script.
In PHP 5.4.45 it produced the XML as stated above. However, under PHP 7.0.5, the following XML is
generated:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Body>
<element1/>
</SOAP-ENV:Body>
For other people affected by this bug, if you replace the buildElement function with the following
code, the generated XML is as expected.
private function buildElement(array &$addTo, array $elements)
{
if (0 === count($elements)) {
return;
}
$element = array_shift($elements);
$addTo[$element] = array();
$this->buildElement($addTo, $elements);
return;
}
Test script:
---------------
<?php
class Example
{
private function buildElement(array &$addTo, array $elements)
{
$previous = & $addTo;
foreach ($elements as $element) {
$previous[$element] = array();
$previous = & $previous[$element];
}
}
public function getSoapData()
{
$soapData = array();
$this->buildElement($soapData, array('element1', 'element2',
'element3', 'element4', 'foo'));
$soapData['element1']['element2']['element3']['element4']['element4']['foo']
= 'bar';
return $soapData;
}
}
$client = new SoapClient("some.wsdl");
$data = (new Example())->getSoapData();
$client->doSomething($data);
Expected result:
----------------
The XML sent to our supplier looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Body>
<element1>
<element2>
<element3>
<element4>
<foo>bar</foo>
</element4>
</element3>
</element2>
</element1>
</SOAP-ENV:Body>
Actual result:
--------------
The XML sent to our supplier looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Body>
<element1/>
</SOAP-ENV:Body>
