SoapClient()'s "stream_context" parameter gets mangled if used in a function. The stream context becomes disfunctional.

Below are two examples listed of which one does not work. Although not quite sure, this might be also related to #46096.

Reproduce code:


// Example 1, emits a warning, mangles value of $ctx.

function getSoapClient_1() {
    $ctx = stream_context_create();
    return new SoapClient(URI, array('stream_context' => $ctx));

// Explicit output not required to see the error/warning.
getSoapClient_1()->__soapCall('Help', array());

// ---

// Example 2, works as far I can see.

$ctx = stream_context_create();

function getSoapClient_2($ctx) {
    return new SoapClient(URI, array('stream_context' => $ctx));

// No output, no warning, seems OK.
getSoapClient_2($ctx)->__soapCall('Help', array());

Expected result:
At least no output as not output is triggered.

Actual result:
"Warning: SoapClient::__doRequest(): XX is not a valid Stream-Context resource in [...]"

Where the XX is the resource number id. Interestingly the output is not "Resource #XX .." but just the number "XX" without the leading hash.

In example 1, the $ctx variable is declared within the scope of the getSoapClient_1() function.  The SoapClient constructor does not make a copy of the stream context.  That stream context resource is destroyed when the function returns.

Patch that copies the stream context if someone wants to review and commit:

Since you are using PHP 5.3 you can use a closure.  The syntax is a little different than something like JavaScript.  Try the following in the meantime:
function getSoapClient_1() {
    $ctx = stream_context_create();
    return function() use ($ctx) {
        return new SoapClient(URI, array('stream_context' => $ctx));

$client = getSoapClient_1();
$client()->__soapCall('Help', array());
