What can replace this design?
There are a lot of similar checks in the code, but I don’t really want to put it into a separate function and this array is taken after processing the xml file.
if(isset($dict_notification->{'purchaseDocumentation'}->{'grantStartDate'})) { $date = $dict_notification->{'purchaseDocumentation'}->{'grantStartDate'}; } else { return; // old - $date = null; } 
or pass it to a separate function; pass an array by reference to it — no problem. Something in the spirit of:
function turboset(&$array, $key, $default=''){ if (!isset($array[$key])){ return $default; } return $array[$key]; } either php7 example from there
<?php // Fetches the value of $_GET['user'] and returns 'nobody' // if it does not exist. $username = $_GET['user'] ?? 'nobody'; // This is equivalent to: $username = isset($_GET['user']) ? $_GET['user'] : 'nobody'; // Coalescing can be chained: this will return the first // defined value out of $_GET['user'], $_POST['user'], and // 'nobody'. $username = $_GET['user'] ?? $_POST['user'] ?? 'nobody'; ?> Source: https://ru.stackoverflow.com/questions/544902/

$date = $dict_notification->{'purchaseDocumentation'}->{'grantStartDate'} ?: null;True, if you havefalse,0,'0', etc. in the variable, then in$datereturnsNULL:( - Vismanfalse,0and'0'are quite correct and, possibly, one of the expected options. It is better to check at the very beginning, after parsing, in one crowd (arrays of expected keys, possible markers, etc.). - user207618$id=$dict_notification->{'id'} ?: return;- users
