IPhpCallable

assembly: Peachpie.Runtime.dll

The interface represents an abstraction of a value converted to callable. It is used internally in order to perform call operation on a value dynamically.

Construction

From	Method
PhpValue	value.AsCallable() Casts given value to a callable according to PHP semantics. Can result in a reference to invalid PhpCallback.
System.Delegate	RoutineInfo.CreateUserRoutine(name, delegate) Creates callable to a delegate.
string	PhpCallback.Create(name) Creates callable to a declared function. When the callable is invoked, function gets resolved within given Context.

Methods

Method	Description
Invoke(Context ctx, params PhpValue[] arguments) : PhpValue	Performs dynamic invocation of the callable object.
ToPhpValue() : PhpValue	Gets PHP representation of the callable. Used internally to print the callable object.

Remarks

The list of declared functions is managed as a set of IPhpCallable instances by Context.

Library functions may accept an argument of type IPhpCallable. It is a well known argument type and the compiler and the runtime will convert passed value to IPhpCallable implicitly using construction.

The compiler implicitly implements IPhpCallable interface on PHP classes defining magic __invoke method.
