How do I generate a SOAP request with recursive capabilities? - php

Question

As I haven't found a solution for testing my SOAP integration, I have decided to make my own soap requests through POST method. The method sends an XML response which works fine, but I want to make my own array-to-xml parser. So far my code is:
private function parseData($xml, $data) {
foreach ($data as $key => $row) {
var_dump($key, $row);
if (is_array($row) && count($row)) {
return $this->parseData($xml, $row);
}
$xml->addChild($key, $row);
}
return $xml;
}
private function toWSDL($call, $data) {
$root = '<data/>';
$xml = new \SimpleXMLElement($root);
$xml = $this->parseData($xml, $data);
$xmlBody = $xml->asXML();
$open = '<ns1:' . $call . '>';
$close = '</ns1:' . $call . '>';
$xmlBody = str_replace('<data>', $open, $xmlBody);
$xmlBody = str_replace('</data>', $close, $xmlBody);
$xmlBody = str_replace('<?xml version="1.0"?>', '', $xmlBody);
$request_data = <<<EOF
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns1="https://api.hostedshop.io/service.php">
<SOAP-ENV:Body>
$xmlBody
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
EOF;
return $request_data;
}
but it does not work for a soap function called "Product_Update", which takes in an array like so:
$this->call("Product_Update", [
"ProductData" => [
"Id" => 1,
"Stock" => 2
]
]);
The "ProductData" key with an array does not work with my parseData function, which is why I am writing for help.
