Is there a way to escape the "." character in php?

Question

I have an stdClass object that I have dynamically created from a JSON using json_decode(). I am trying to access a field by calling $value->V.X->processedField but this field has a period. This is giving me a syntax error. Is there a way to somehow escape the period in my code, or am I going to have to rename the field in my JSON?

<?php
// example code

$value = json_decode('{"V.X": {"processedField":"the value"}}');
print_r($value->{"V.X"}->processedField);
// or 
$var = "V.X";
print_r($value->$var->processedField);

Some of these sort of questions have been asked repeatedly before, please try not to just answer without checking first. – Nigel Ren Jun 10 '21 at 16:42

It's a common thing, the idea is to just focus the answers to limit the repetition. – Nigel Ren Jun 10 '21 at 19:58
