Invalid argument supplied for foreach() when using parser

the following example from the documentation sends folgwenden error: CRITICAL - 2020-02-19 14:50:57 --> Invalid argument supplied for foreach()

$template = '{name} lives in {location}{city} on {planet}{/location}.';

$data = [
        'name'    => 'George',
        'location' => [ 'city' => 'Red City', 'planet' => 'Mars' ]
];

echo $parser->setData($data)->renderString($template);
// Result: George lives in Red City on Mars.

Dear MikiStoni,

There is a typo in the documentation. Location should be enclosed in additional square brackets to form an array, e.g.

PHP Code:

$data = [
        'name'    => 'George',
        'location' => [['city' => 'Red City', 'planet' => 'Mars']]
]; 


This comes because Parser expects attribute to be either a string (like George), or an Array-of-Arrays (e.g. $location[0] = ['city' => 'Red City', 'planet' => 'Mars']) in order to be able to iterate over it, and then process each pair inside the outer array as normal key:value pair like it was processing 'name'=>'George' pair before.

Probably topicstarter should do the same with errors array, and enclose it into additional array.
