SPX, which stands for Simple Profiling eXtension, is just another profiling extension for PHP. It differentiates itself from other similar extensions as being totally free and confined to your infrastructure (i.e. no data leaks to a SaaS). Very simple to use: just set an environment variable (command line) or switch on a radio button (web request) to profile your script. Thus, you are free of manually instrumenting your code (Ctrl-C a long running command line script is even supported). Using a dedicated browser extension or command line launcher. Multi metrics capable: 22 are currently supported (various time & memory metrics, included files, objects in use, I/O...). Able to collect data without losing context. For example Xhprof (and potentially its forks) aggregates data per caller / callee pairs, which implies the loss of the full call stack and forbids timeline or Flamegraph based analysis.

webStraktor is a programmable World Wide Web data extraction client. Its purpose is to scrape HTML based content via the HTTP protocol and extract relevant information. webStraktor features a scripting language to facilitate the collection, the extraction and the storage of information available on the web, including images. The scripting language uses elements of the Regular Expression and xPath syntax. The webStraktor scripting language has a small instruction set and its syntax is easy to master. The standard webStraktor output format is XML based, either in ASCII, UTF-8 or ISO-8859-1 (Latin1) code pages. webStraktor relies on the Apache HttpClient for retrieving content via the HTTP protocol. It adheres to the Robots Exclusion Protocol and it can be configured to operate in an anonymous way by connecting to the predominant types of web proxy servers. webStraktor extends the functionality of web crawlers, spiders or bots by integrating scraping and crawling capabilities.
