How to write property paths

We use Symfony's PropertyAccess component to help read and write data.

Array properties

To access array properties use the index notation, specifying array keys within square brackets.

Access $data['name']:

[name]

Access $data['people']['name']:

[people][name]

Access $data['people']['categories'][0]:

[people][categories][0]

Object properties

To access object properties use the dot notation, specifying object properties separated by a dot character.

Access $data->name:

name

Access $data->people->name:

people.name

Access $data->people->categories[0]:

people.name.categories[0]
