char CData can't be directly assigned a number

Description

The following code:

<?php

$v = FFI::new("char[2]");
$v[0] = 65;
var_dump($v);

Resulted in this output:

Fatal error: Uncaught FFI\Exception: Incompatible types when assigning to type 'char' from PHP 'int' in Command line code:1
Stack trace:
#0 {main}
  thrown in Command line code on line 1

But I expected this output instead:

object(FFI\CData:char[2])#1 (2) {
  [0]=>
  string(1) "A"
  [1]=>
  string(1) ""
}

It's somewhat weird to have to type cast around, i.e. I could just do a FFI::cast to uint8_t * and it works. But for some reason, char is special. Seems like an arbitrary restriction to me, and it really should accept both.

Riprodurre l’esempio PHP FFI dell’issue e tracciare la gestione delle assegnazioni a un valore CData di tipo char. Individuare l’implementazione FFI pertinente e i test FFI esistenti, quindi aggiungere la copertura per l’assegnazione di un intero a char e verificare che venga prodotto il valore di carattere previsto.
