kingbes / phpc example snippets



Kingbes\Phpc\Library;
use Kingbes\Phpc\CData;
use Kingbes\Phpc\SafeCall;
use Kingbes\Phpc\Memory;

$ffi = Library::load('libc', 'int strlen(const char*); void* malloc(size_t); void free(void*);');

// 用 CData::owned 包装 malloc 返回的指针，析构自动 FFI::free
$buf = $ffi->malloc(16);
$wrapped = CData::owned($buf);

// 安全地填充 C 字符串
Memory::copy($wrapped->raw(), 'hello', 5);
$wrapped->raw()[5] = "\0";

// 安全调用 strlen
$len = SafeCall::invoke($ffi, 'strlen', [$wrapped->raw()]);
echo $len; // 5

// 即使忘记 release，析构也会自动 free
$wrapped->release();


use Kingbes\Phpc\Phpc;

$ffi = Phpc::load('libc', 'int strlen(const char*);');
echo Phpc::call($ffi, 'strlen', [Phpc::toString('hello')]);
