This is creating an array with a single element. The element is a reference to the object from which it is executed it. For more information see the documentation on passing by reference.

It's a construct that initializes an array which contains one element: a reference to the object the array is initialized in. Inside every class, you can refer to the "current" instance using $this.

Its PHPs pass by reference construction. Typically this means that a reference to the parameter is passed to the function instead of a copy of the value, so that modifications inside the function affect the object.
