How to Insert Multiple Items in a Laravel Collection Inside a PHP Loop

When working with Laravel and collections, you may encounter situations where you want to insert multiple items in a collection inside a PHP loop. If you've ever faced a scenario where only the last item gets added, you're not alone. In this post, we'll explore how to resolve this issue and successfully insert all desired items in a Laravel collection.

The Problem

Imagine you have an array, $some_array, filled with values such as 1, 2, 3, and 4. You want to insert these values into a Laravel collection, but you notice that only the last entry is being saved. This is a common mistake when looping through arrays and trying to create collections.

Example Issue

Consider the following code snippet:

With this approach, an empty collection is reinitialized in each iteration of the loop, which leads to only the last item being retained.

The Solution

To effectively insert multiple items into a Laravel collection while iterating through your array, we should follow these steps:

Step 1: Import the Collection Class

At the top of your PHP file, include the Laravel collection class, Illuminate\Support\Collection. This allows you to utilize the collection methods easily.

Step 2: Initialize the Collection

Before entering the loop, create a new instance of the collection. This ensures that you start with an empty collection that persists throughout the loop iterations:

Step 3: Iterate and Push Items

Inside your loop, instead of reinitializing the collection, you can use the push method to add each new object to your collection:

Final Output Check

After the loop, you can utilize the all() method to retrieve all items stored in the collection for verification:

Conclusion

By following these steps, you can efficiently insert multiple items into a Laravel collection inside a PHP loop. You'll end up with a collection that captures all intended items rather than overwriting them with every iteration. Remember to always initialize your collections outside of the loop and use the push method to add items to ensure that none are missed.
