php_mine_class is a class that hides you from the work of parsing an email regarding MIME RFCs manually. Instead, you can throw in your raw email, and get back a nice object with all header fields and all MIME blocks. This is most suitable for people writing email clients in PHP, who dont want to use IMAP support in PHP for MIME handling.
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).
php_template is a very fast and easy to use PHP template rendering system. It can create large amounts of data quickly, given a simple template. It supports dynamic data tags for things like table data and lists, optional tags for conditional data presentation, and simple variable tags.
