Extract a single column from a list of associative arrays into a flat list. Common transformation for SELECT results — equivalent to array_column with optional indexing key.
PHP
<?php
function pluck(array $rows, string $col, ?string $indexBy = null): array {
return array_column($rows, $col, $indexBy);
}
$users = [
['id'=>1,'name'=>'Alice'],
['id'=>2,'name'=>'Bob'],
['id'=>3,'name'=>'Cara'],
];
print_r(pluck($users, 'name')); // [Alice, Bob, Cara]
print_r(pluck($users, 'name', 'id')); // [1=>Alice, 2=>Bob, 3=>Cara]Save your own code snippets
