 [2012-12-15 18:06 UTC] php dot maks3w at virtualplanets dot net
Description:
------------
Situation: Custom class which extend from SoapClient and override "public 
function __doRequest($request, $location, $action, $version, $one_way = null)"

$request can't be used to compare strings, instead throw a Segmentation Fault 
error.

$request looks like a C Pointer or any other type instead of a PHP String type

As workaround you can filter the variable passing the value through a function 
which return basically the same value of the argument passed as input (like 
ltrim) after that it's possible save the returned value and now is a normal PHP 
String and can be compared.

Test script:
---------------
FAILING CODE:
public $lastRequest;

function __doRequest($request, $location, $action, $version, $one_way = 0) {
    $this->lastRequest = $request;
}

$this->assertEquals('SomeContent', $this->lastRequest); // Segmentation Faul.


WORKAROUND:
public $lastRequest;

function __doRequest($request, $location, $action, $version, $one_way = 0) {
    $this->lastRequest = ltrim($request); // Pass $request through a function
}

$this->assertEquals('SomeContent', $this->lastRequest); // Works
