PHPMailer
The classic email sending library for PHP
PHPMailer – A full-featured email creation and transfer class for PHP. Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings. SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Validates email addresses automatically. Many PHP developers need to send email from their code. The only PHP function that supports this directly is mail(). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong, if not unsafe! -

Dompdf
HTML to PDF converter for PHP
dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer, it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries. -

PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc. Support for PHP versions will only be maintained for a period of six months beyond the end of life of that PHP version. Use composer to install PhpSpreadsheet into your project. Or also download the documentation and samples if you plan to use them. A good way to get started is to run some of the samples. Don't forget to download them via --prefer-source composer flag. And then serve them via PHP built-in webserver. PhpSpreadsheet relies on Composer autoloader. So before working with PhpSpreadsheet in standalone, be sure to run composer install. -

mPDF
PHP library generating PDF files from UTF-8 encoded HTML
mPDF is a PHP library that generates PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files ‘on-the-fly’ from his website, handling different languages. It is slower than the original scripts e.g. HTML2FPDF and produces larger files when using Unicode fonts, but support for CSS styles etc. and has been much enhanced. Supports almost all languages including RTL (Arabic and Hebrew), and CJK (Chinese-Japanese-Korean). Nested block-level elements (e.g. P, DIV) including margins, borders, padding, line height, background colors, etc. Right-to-left languages are supported, with automatic detection of RTL characters within a document. Transposes tables, lists, text justification, and table cell alignment, as well as a full-text reversal for RTL characters. Automatically detects non-RTL characters and displays these in the original order. -

ReflectionDocBlock
Component of phpDocumentor that provides a DocBlock parser
The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser that is 100% compatible with the PHPDoc standard. With this component, a library can provide support for annotations via DocBlocks or otherwise retrieve information that is embedded in a DocBlock. In order to parse the DocBlock one needs a DocBlockFactory that can be instantiated using its createInstance factory method. Then we can use the create method of the factory to interpret the DocBlock. Please note that it is also possible to provide a class that has the getDocComment() method, such as an object of type ReflectionClass, the create method will read that if it exists. The create method will yield an object of type \phpDocumentor\Reflection\DocBlock whose methods can be queried. The composer requires phpdocumentor/reflection-docblock. -

reCAPTCHA
PHP client library for reCAPTCHA, a free service
reCAPTCHA is Google’s human-verification system that helps websites distinguish real users from automated abuse while keeping friction low for legitimate traffic. The project bundles client and server examples, language-specific helpers, and documentation patterns for integrating reCAPTCHA v2 and v3 flows into web forms and APIs. Its design philosophy is “risk-based”: most users pass silently based on behavioral signals, while higher-risk interactions may be challenged with an image, checkbox, or other verification step. Site owners register keys, embed a small client script, and verify tokens on the server to protect actions like sign-ups, logins, and form submissions. The ecosystem supports mobile and enterprise variants, but the repo focuses on common web integrations and best practices for verifying the token securely. Deployed correctly, reCAPTCHA reduces credential stuffing, bot sign-ups, and scraping without degrading the experience for typical users. -

ramsey/uuid
A PHP library for generating universally unique identifiers (UUIDs)
ramsey/uuid is a PHP library for generating and working with RFC 4122 version 1, 2, 3, 4, and 5 universally unique identifiers (UUID). ramsey/uuid also supports optional and non-standard features, such as version 6 UUIDs, GUIDs, and other approaches for encoding/decoding UUIDs. A universally unique identifier, or UUID, is a 128-bit unsigned integer, usually represented as a hexadecimal string split into five groups with dashes. The most widely-known and used types of UUIDs are defined by RFC 4122. The probability of duplicating a UUID is close to zero, so they are a great choice for generating unique identifiers in distributed systems. UUIDs can also be stored in binary format, as a string of 16 bytes. The JSON extension is normally enabled by default, but it is possible to disable it. Other required extensions include PCRE and SPL. These standard extensions cannot be disabled without patching PHP’s build system and/or C sources. -

TypeResolver
PSR-5 based resolver of class names, types, structural element names
The specification on types in DocBlocks (PSR-5) describes various keywords and special constructs but also how to statically resolve the partial name of a Class into a Fully Qualified Class Name (FQCN). PSR-5 also introduces an additional way to describe deeper elements than Classes, Interfaces and Traits called the Fully Qualified Structural Element Name (FQSEN). Using this it is possible to refer to methods, properties and class constants but also functions and global constants. This package provides two Resolvers that are capable of returning a series of Value Object for given expression while resolving any partial class names, and returning an FQSEN object after resolving any partial Structural Element Names into Fully Qualified Structural Element names. Consult the examples folder and check which type of action that your want to accomplish. -

Doctrine Lexer
Base library for a lexer that can be used in Recursive Descent Parsers
PHP Doctrine Lexer parser library that can be used in Top-Down, Recursive Descent Parsers. This lexer is used in Doctrine Annotations and in Doctrine ORM (DQL). To write your own parser you just need to extend Doctrine\Common\Lexer\AbstractLexer and implement three abstract methods. These methods define the lexical catchable and non-catchable patterns and a method for returning the type of a token and filtering the value if necessary. The Lexer is responsible for giving you an API to walk across a string one character at a time and analyze the type of each character, value and position of each token in the string. The low level API of the lexer is pretty simple. The setInput($input) option sets the input data to be tokenized. The Lexer is immediately reset and the new input tokenized. And the option glimpse(), peeks at the next token, returns it and immediately resets the peek. -
