PHPExcel
Library offering classes to read from and write to spreadsheet formats
PHPExcel is a comprehensive library for reading, writing, and manipulating Excel spreadsheets in PHP, supporting multiple formats like XLS, XLSX, CSV, and more. Developers can create complex spreadsheets with styled cells, formulas, charts, images, and multiple sheets programmatically. It also supports reading existing files, iterating through cells, applying data validation, and converting between formats. Because it handles the details of Excel file structures—including relationships, themes, and various metadata—users don’t need to manage proprietary file internals themselves. The API allows for cell access using row/column indexes or column letters, batch updates, and streaming writes to reduce memory usage. As a mature library, it’s used in reporting, migrations, invoice generation, and any scenario where dynamic, server-side spreadsheet generation is needed in PHP applications. -

Twemoji
Simple library that provides standard Unicode emoji for all platforms
Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope. -
