Calling PHP functions returns null

[ond1]

Hi,

I am working on a XSLT with PHP project which involves allowing the user the possibility to write their own extension function. The problem I am hitting is on the C++ side the function (i.e. userFunction) is always returning null. I am currently working from PPH-CPP-LEGACY. Any ideas what I am doing wrong.

In PHP:

// define a user space function function userFunction($param) { echo("userspace function called with no param\n"); return "user function - data"; }

In C++:

`jobject JNICALL PHP_SaxonProcessor::phpNativeCall
(JNIEnv *env, jstring funcName, jobjectArray arguments, jobjectArray arrayTypes){

const char *nativeString = SaxonProcessor::sxn_environ->env->GetStringUTFChars(funcName, NULL);

Php::Value data = Php::call(nativeString, 'something');

SaxonProcessor::sxn_environ->env->ReleaseStringUTFChars(funcName, nativeString);
if(data == NULL) {
return NULL;
} else {
return SaxonProcessor::sxn_environ->env->NewStringUTF(dataChar);
}
}`

Update:
What I have noticed is the php function is executed but just not returning a value. As mentioned before a null is returned.

I have similar problem with lambda functions. Using the example http://www.php-cpp.com/documentation/lambda-functions, lambda function is called, but in C++/PHP is returned NULL value (even If i simple give "return 1;" statement at the beginning of the lambda function).

Tested with PHP 7.0 and PHP 7.1.

Update: Tested latest version with PHP 7.2 and it works!
