PHP マニュアル: Wrap a PHP callable in a LuaSandboxFunction

public LuaSandboxFunction LuaSandbox::wrapPhpFunction(callable $function)

Wraps a PHP callable in a LuaSandboxFunction, so it can be passed into Lua as an anonymous function.

The function must return either an array of values (which may be empty), or null which is equivalent to returning the empty array.

Exceptions will be raised as errors in Lua, however only LuaSandboxRuntimeError exceptions may be caught inside Lua with pcall() or xpcall().

For more information about calling Lua functions and the return values, see LuaSandboxFunction::call.

Returns a LuaSandboxFunction.
