FFI::new

    (PHP 7 >= 7.4.0, PHP 8)

    FFI::new — Creates a C data structure

    Description

    publicFFI::new(FFI\CType|string$type, bool$owned = true, bool$persistent = false): ?FFI\CData

    Creates a native data structure of the given C type. Any type declared for the instance is allowed.

    Parameters

    type

    type is a valid C declaration as string, or an instance of FFI\CType which has already been created.

    owned

    Whether to create owned (i.e. managed) or unmanaged data. Managed data lives together with the returned FFI\CData object, and is released when the last reference to that object is released by regular PHP reference counting or GC. Unmanaged data should be released by calling FFI::free(), when no longer needed.

    persistent

    Whether to allocate the C data structure permanently on the system heap (using malloc()), or on the PHP request heap (using emalloc()).

    Return Values

    Returns the freshly created FFI\CData object, or null on failure.
