Laravel Eloquent - Get one Row

This might be a simple question, but I cannot figure this out. I am trying to get a user by email using:

$user = User::whereEmail($email)->get();

But this is returning an array (of dimension 1) of $users. So If I want to get the name, I have to do $user[0]['first_name'].

I tried using limit(1) or take(1), or even using ->toArray() but there was no difference.

What am I doing wrong?

You want to get one row from queried result? Or you just want one row from database query?

Simply use this:

$user = User::whereEmail($email)->first();

You can do this too

Before you use this you must declare the DB facade in the controller Simply put this line for that

use Illuminate\Support\Facades\DB;

Now you can get a row using this

$getUserByEmail = DB::table('users')->where('email', $email)->first();

or by this too

$getUserByEmail = DB::select('SELECT * FROM users WHERE email = ?' , ['useremailaddress@email.com']);

This one returns an array with only one item in it and while the first one returns an object. Keep that in mind.

Hope this helps.

Using Laravel Eloquent you can get one row using first() method,

it returns first row of table if where() condition is not found otherwise it gives the first matched row of given criteria.

Syntax:

Model::where('fieldname',$value)->first();

Example:

$user = User::where('email',$email)->first(); 
//OR
//$user = User::whereEmail($email)->first();

In case you need to find out any specific field, you can use

$user = User::where('email',$email)->first(); 

$user = User::where('username',$username)->first(); 

$user = User::where('id',$id)->first();

Try with it

$color = \App\Color::take(1)->first();

If you don't even need an entire row, you may extract a single value from a record using the value() method. This method will return the value of the column directly:

$first_name = DB::table('users')->where('email' ,'me@mail,com')->value('first_name');

Laravel 5.2

$sql = "SELECT * FROM users WHERE email = $email";

$user = collect(\User::select($sql))->first();

or

$user = User::table('users')->where('email', $email)->pluck();

This will load all the users from your database into the web application server's memory, and possibly cause it to crash if you have more user data than you can store in your server's RAM. You only need one user, so no need to waste memory on all of them. Instruct the database to send you the first user only with $user = User::whereEmail($email)->first(); as proposed in the accepted answer.
