php 5.6 constant syntax not supported

[tystr]

I have a constant defined like this:

    const MONTHS = [
        'January'   => 'January',
        'February'  => 'February',
        // ...
    ];

pdepend errors with the following message:
Unexpected token: =>

In another file I have a constant defined like this:

    const SCALAR_TYPES = ['string', 'int', 'float', 'boolean'];

pdepend errors with the following message:
Unexpected token: 'int'
