Syntax to get single column value in laravel

Start by importing your Eloquent model at the beginning of your file. This ensures seamless interaction with the database. Then, Utilize the value method on your model to fetch the desired column value. Follow this step-by-step process:

use App\Models\YourModel;

// Replace 'your_column_name' with the actual column name
$columnName = 'your_column_name';

// Use the model to retrieve the single column value
$singleValue = YourModel::where('some_condition', 'some_value')->value($columnName

Here Post is the name of your model you can replace it with your model and we added few conditions using where clause. title is the column name which you want to fetch the value. Ensure you replace 'some_condition' and 'some_value' with the appropriate conditions for your use case.

Let’s illustrate this with a practical example involving the User model. Suppose we want to retrieve the ’email’ column for a user with id equal to 1:

use App\Models\Post;

$Post = Post::where('some_condition', 'some_value')->value("title");
