Eloquent get only one column as an array

Getting Only One Column as a One-Dimensional Array in Laravel 5.2 Using Eloquent

Are you struggling to get only one column as a one-dimensional array in Laravel 5.2 using Eloquent? Don't worry, you're not alone! Many developers face this issue when working with Eloquent.

The Problem

Let's take a look at the code snippet you provided:

$array = Word_relation::select('word_two')->where('word_one', $word_id)->get()->toArray();

This code seems logical at first, as it selects only the "word_two" column from the "Word_relation" table where "word_one" matches a given $word_id. However, the result is not what we expect. Instead of a one-dimensional array, we end up with a two-dimensional array like this:

array(2) {
    [0]=>
    array(1) {
        ["word_one"]=>
        int(2)
    }
    [1]=>
    array(1) {
        ["word_one"]=>
        int(3)
    }
}

The Solution

To get only one column as a one-dimensional array, you can make use of the pluck() method provided by Laravel's Eloquent. Here's how you can modify your code:

$array = Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();

Using the pluck() method, we first filter the records where "word_one" matches the given $word_id. Then, we specify the specific column we want to retrieve, which is "word_two" in this case.

Now, let's see the result you're looking for:

array(2) {
    [0]=> 2
    [1]=> 3
}

Voila! You successfully obtained a one-dimensional array with only the "word_two" column values.

Wrapping Up

Getting only one column as a one-dimensional array in Laravel 5.2 is a common issue, but thankfully there's a simple solution. By using the pluck() method, you can easily retrieve the desired column values.

Next time you find yourself facing this problem, remember to modify your Eloquent query using the pluck() method. It will save you time and headaches!
