# LuaSandbox::wrapPhpFunction

(PECL luasandbox >= 1.2.0)

LuaSandbox::wrapPhpFunction — Wrap a PHP callable in a LuaSandboxFunction

### Description

public LuaSandbox::wrapPhpFunction ( callable `$function` ) : LuaSandboxFunction

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().

### Parameters

`function`

  Callable to wrap.

### Return Values

Returns a LuaSandboxFunction.
