Dump

dump_if() - an extended dump()

<?php

use Illuminate\Console\Command;

if (! function_exists('dump_if')) {
    /**
     * Do a dump if a condition is true. Also, support output to
     * an Illuminate\Console\Command instance. And support printf-like args.
     * If you want to output to a command instance, pass it as the last parameter,
     * along with an optional command output method ('info', 'warn', 'error' etc).
     * So if using from within a database seeder, you can use $seeder->command as
     * the command instance.
     *
     * Examples:
     *
     *      dump_if($cond, $data);
     *      dump_if($cond, 'My user id is %05d', Auth::user()->getKey())
     *      dump_if($cond, 'My user id is %05d', Auth::user()->getKey(), $seeder->command)
     *      dump_if($cond, 'My user id is %05d', Auth::user()->getKey(), $seeder->command, 'warn')
     *
     * @param bool $cond
     * @param array ...$args
     */

        } else {

    }
