Laravel chunkById and lazy: process large tables without running out of memory
PHP Dasun Kalupahana 70 views
<?php
User::chunkById(1000, function ($users) {
foreach ($users as $user) {
// process $user
}
});
foreach (User::lazy() as $user) {
// streamed one at a time
}Loads rows in batches instead of all at once, so big tables don’t exhaust memory. Prefer chunkById when you update rows while looping.
