function (Blueprint $table), Is $table a variable/property / object??? Which class's object/ va-CodePudding

Schema::create('flights', function (Blueprint $table) { $table->increments('id'); $table->string('name'); $table->string('airline'); $table->timestamps(); });

CodePudding user response：

Well, $table is an instance of \Illuminate\Database\Schema\Blueprint which can be found here : vendor/laravel/framework/src/Illuminate/Database/Schema/Blueprint.php

All available methods can be found in that class.

Just for proof, here is the class : Log::info(get_class($table);

Result [2022-04-06 10:09:52] local.INFO: Illuminate\Database\Schema\Blueprint

Here is the result of available methods : Log::info(json_encode(get_class_methods($table)));

Result :
