Laravel chunkById and lazy: process large tables without running out of memory

PHP Dasun Kalupahana 69 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.
