HTML Forms generation and validation is a PHP class that generates HTML forms supporting many built-in validation types on server and client sides. It prevents security attacks by discarding spoofed values, has multiple submit protection, outputs HTML for fields displayed as fully accessible or in read-only mode, and has field value filtering and reformatting. It can be extended with custom control plug-ins. AJAX based form submission, upload monitor progress bar, auto-complete text input, automatic layout renderer, calendar date, CAPTCHA, Google Maps world location selection, linked select, and animation effects plug-ins are available.
PHP OAuth API authorizes user access using the OAuth protocol. It abstracts OAuth 1.0, 1.0a, and 2.0 in the same class. It provides built-in support for popular OAuth servers: 37Signals, Amazon, Buffer, Bitbucket, Box.net, Discogs, Disqus, Dropbox with OAuth 1.0 and 2.0, Etsy, Eventful, Facebook, Fitbit, Flickr, Foursquare, github, Google with OAuth 1.0a and OAuth 2.0, Instagram, LinkedIn, Microsoft, Rdio, Reddit, RightSignature, Salesforce, Scoop.it, StockTwits, SurveyMonkey, Tumblr, Twitter, VK, Withings, Xero, XING, and Yahoo!. Every other OAuth server is supported by setting an endpoint URLs and other parameters using specific class variables or an external JSON configuration file. The class can also send requests to an API using the previously-obtained OAuth access token. For servers which support offline access, the class can renew expired tokens automatically using refresh tokens.
PHP Text Diff Highlight class can find and view the difference between text strings. It takes two text strings and uses the diff algorithm to find the differences between them and return a list of changes to patch the original string to become the final string. The patch list shows what text should be added or removed to change one string into the other. The difference between the text strings may be computed in three modes: by character, by word, or by line. The class may also format the strings to view them as HTML, showing which characters are added and removed with special insertion and deletion styles. The example page works as a tool to interactively view the changes as the user changes the texts before and after the changes are applied.
php_mt_seed finds possible seeds given the very first PHP mt_rand() output after possible seeding with mt_srand(). With advanced invocation modes, php_mt_seed is also able to match multiple, non-first, and/or inexact mt_rand() outputs to possible seed values. php_mt_seed is written in C with optional SIMD intrinsics (SSE4.1/AVX, XOP, AVX2, MIC) and OpenMP. On a modern quad-core CPU, it is able to search the full 32-bit seed space in one minute (or in just seven seconds on Xeon Phi).
PHPDF is a toolkit for creating PDF reports in PHP. It takes care of dividing your data into pages, adding page headers and footers if desired. Widow/orphan protection is also built in. It loads quickly and has a low memory footprint. It has a built-in PDF document writer, so it doesn't need an external library.
