How to select all column name from a table in laravel?

Just in-case if you have multiple databases connections, try following:

Add in the top of your php script

use Illuminate\Support\Facades\Schema;

Retrieve anywhere in your code

With Database Connection

$columns = Schema::Connection('business')->getColumnListing('users'); // 'business' is your database connection

        echo "<pre>";
        print_r($columns);
        exit();

Without Database Connection

$columns = Schema::getColumnListing('users');

    echo "<pre>";
    print_r($columns);
    exit();

Get Table Name From Model

$product = new Product;
$table = $product->getTable();
print_r($table);

Get Table Column Name From Model

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{   
    public function getTableColumns() {
        return $this->getConnection()->getSchemaBuilder()->getColumnListing($this->getTable());
    }
}

Now you will get all columns of "products" table and if you need it in controller then you can get it by following way :

 $product = new Product;
 $columns = $product->getTableColumns();
 print_r($columns);

As of Laravel 6.x this works:

                    $db = DB::connection()->getPdo();
                    $rs = $db->query('SELECT * FROM Teller LIMIT 0');
                    for ($i = 0; $i < $rs->columnCount(); $i++) {
                            $col = $rs->getColumnMeta($i);
                            $columns[] = $col['name'];
                    }
                    print_r($columns);

The hint here is just to go around eloquent (which should just provide a simple way to do this, but clearly does not) and grab the PDO object and then use the answer from the same question for straight PDO access

This will also work when there is no database selected by replacing 'Teller' with databasename.Teller

HTH,

You can get all columns name by simply doing that...

use Illuminate\Support\Facades\Schema;

use Illuminate\Support\Facades\DB;

public function getTableColumns($table)
{
    return DB::getSchemaBuilder()->getColumnListing($table);

    // OR

    return Schema::getColumnListing($table);

}
