I got an array like:
$array = ['foo'=>['bar' => ['value' => 'test']]];
Now I would like to get the value:
echo $array['foo']['bar']['value']; // 'test'
Now my problem begins: Sometimes the array is missing some parts. Like bar. Now I would get an error, because the index bar does not exist.
I can do an array_key_exists search in this. But I'd also have to do this on foo and value.
So my question is: Is there a good way to check the "chain" of array indices?
My first try was something like
strpos(json_encode($array), 'value') > 0
But this is returns a false positive if an array like
$array = ['foo'=>['value' => 'test']];
echo $array['foo']['bar']['value']; // error
comes up.
