Flatten Multi-Dimensional Array

Convert a nested, multi-dimensional PHP array into a single-dimensional, flat array for easier iteration and processing.

Sort Associative Array by Key Value

Sort an array of associative arrays based on the values of a specific key (e.g., sorting a list of products by price or name) in ascending or descending order.

Recursively Merge Multiple Arrays

Combine multiple PHP arrays, including nested arrays, into a single array, prioritizing values from later arrays for common keys, useful for configuration.

Filter Array and Re-index Numerically

Filter elements from a PHP array based on a callback function and then re-index the resulting array numerically, useful for creating clean lists.

Implement a Repeating Interval with `useInterval` React Hook

Create a custom React `useInterval` hook to easily manage `setInterval` logic within your components, ensuring proper cleanup on unmount and preventing memory leaks.

Attach and Clean Up Event Listeners with `useEventListener` React Hook

Create a reusable `useEventListener` React hook to easily attach and remove DOM event listeners, improving component lifecycle management and preventing memory leaks.

Execute Code on Component Mount and Unmount with Custom Hooks

Implement `useMount` and `useUnmount` React hooks to run specific logic exactly once when a component is mounted or unmounted, mimicking class component lifecycles.

Safely Use `useLayoutEffect` in SSR Environments with `useIsomorphicLayoutEffect`

Implement `useIsomorphicLayoutEffect` to conditionally use `useLayoutEffect` on the client-side and `useEffect` on the server-side, preventing SSR warnings in React.

Detect Key Presses Globally with the `useKeyPress` React Hook

Create a `useKeyPress` hook to easily monitor the state of specific keyboard keys (pressed or not) across your React application for interactive UIs.
