Rekey a list of rows by one of their column values, so $byId[42] gives the row with id=42. Equivalent to array_column($rows, null, $key).
PHP
<?php
function indexBy(array $rows, string $key): array {
$out = [];
foreach ($rows as $row) {
if (isset($row[$key])) $out[$row[$key]] = $row;
}
return $out;
}
$users = [
['id'=>10,'name'=>'Alice'],
['id'=>20,'name'=>'Bob'],
];
$byId = indexBy($users, 'id');
echo $byId[20]['name']; // BobSave your own code snippets
