PHP Snippets.

Creating or Retrieving Models with Eloquent `firstOrCreate` and `firstOrNew`

Discover Laravel Eloquent's `firstOrCreate` to find or create a model, and `firstOrNew` to instantiate a model without saving, for flexible data management.

Filtering PHP Arrays with a Custom Callback

Learn how to filter elements from a PHP array using `array_filter` and a custom callback function, allowing precise data selection based on your specific criteria and logic.

Sorting Multi-Dimensional PHP Arrays by Key

Discover how to sort complex PHP arrays of associative arrays (e.g., list of users) by a specific key's value using `usort` and a custom comparison function for precise ordering.

Extracting a Column from a PHP Array of Arrays

Quickly retrieve all values from a specific column across an array of associative arrays in PHP using `array_column`, ideal for lists of records like user data or product information.

Managing Eloquent Models with Soft Deletes

Learn how to implement soft deletes in Laravel Eloquent models, allowing you to gracefully "delete" records without permanent data loss, and how to query, restore, or force delete them.

Filtering Eloquent Models by Related Model Conditions with `whereHas`

Learn how to filter your main Eloquent models based on the existence or specific conditions of their related models using `whereHas` and `orWhereHas` methods in Laravel.

Implementing Custom Eloquent Casts for Value Objects

Extend Laravel Eloquent's casting system by creating custom cast classes, allowing you to map complex database columns (like currency amounts or geographic coordinates) to PHP value objects.

Applying Application-Wide Query Constraints with Eloquent Global Scopes

Implement Eloquent global scopes to automatically apply query constraints to all queries for a specific model, useful for multi-tenancy, soft deletes, or general data filtering.

Efficient Eager Loading with Conditional Constraints

Optimize Laravel Eloquent queries by eager loading relationships with specific conditions, reducing N+1 issues and memory usage for relevant data.

Reusable Query Logic with Laravel Eloquent Local Scopes

Define and reuse common query constraints across your Laravel Eloquent models using local scopes, promoting DRY principles and cleaner code.

Implementing Laravel Eloquent Polymorphic One-to-Many Relationships

Connect a single model to multiple other models using a polymorphic one-to-many relationship in Laravel Eloquent, ideal for versatile associations like comments or notifications.

Efficient Aggregation of Related Models with Eloquent `withCount` and `withSum`

Optimize performance by retrieving aggregate values (like counts or sums) for related models without loading all relationships, directly within your main query.
