Using $this for default value in php

Question

public function addSpouse($name = ($this->data['gender'] == MALE && empty($name)) ? 'Wife' : 'Husband', $suggest = false)

PHP is following for the above line:

syntax error, unexpected '$this' (T_VARIABLE)

$this is not allowed in function parameter?

EDIT: function is inside a class

Of course, not. `$this` is a reference to the instance of a class. What are you going to refer to, if there is no object? — abcdn, Mar 05 '17 at 11:08

You cannot use a variable ($this->data or any variable) as a default parameter value. Default function parameter values must be constants.

public function addSpouse($name = 'Wife')

is correct but not:

public function addSpouse($name = $data)
