Passing string values by reference back to PHP

[Justas-S]

I am aware that using Php::ByRef in the method argument definition, values can be passed by reference and then cast to char * to avoid copying. Is it possible to achieve the same in the opposite direction: return a char * reference back to PHP?

One way I could see achieving this is passing another variable from PHP to use as the return value. Something like:

<?php

$out = null;
method(in, &out);

void method (Php::Parameters &params)
{
   const char *input = params[0];
   // Process it somehow to produce a new result
   memcpy(params[1].buffer(), new_value, new_value_size);
}

I am not certain if this would work, but a more PHP-friendly solution is still preferred.

I dont know by heart, can you experiment with this yourself? Maybe if you do something like this:

void method (Php::Parameters &params)
{
    // maybe this works?
    params[0] = "a new value";

    // or this?
    params[0] = std::string("a new value");
}
