(PHP 7 >= 7.4.0)

FFI::newCreates a C data structure

Description

public static FFI::new ( mixed $type [, bool $owned = TRUE [, bool $persistent = FALSE ]] ) : FFI\CData
public FFI::new ( mixed $type [, bool $owned = TRUE [, bool $persistent = FALSE ]] ) : FFI\CData

Creates a native data structure of the given C type. If this method is called statically, it must only use predefined C type names (e.g. int, char, etc.); if the method is called as instance method, 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.
