I rely on this often when remapping data for analysis. These scripts are
run a handful of times and discarded. Autovivication keeps the code short.
Here's a snippet I wrote yesterday:
$out = [];
while ($row = $res->fetchAssociative()) {
// ...
$docId = $row['document_id'];
if (!isset($out[$docId])) {
$out[$docId] = [
'application_id' => $row['application_id'],
'document_id' => $docId,
'filename' => $row['filename'],
];
}
$out[$docId]['labels'][$row['document_rejection_reason_id']] =
true;
}
Naturally I would prefer to keep this behaviour for arrays.
