NoiseByNorthwest/php-spx: A simple & straight-to-the-point PHP profiling extension with its built-in web UI

פורסם ב: by

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 page) 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: 21 currently supported (various time metrics, memory, 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.
  • shipped with its web UI which allows to:
    • enable / configure profiling for the current browser session
    • list profiled script reports
    • select a report for in-depth analysis, featuring these interactive visualizations:
      • timeline (scale to millions of function calls)
      • flat profile
      • Flamegraph

Check your PHP project for known security issues – SensioLabs Security Advisories Checker

פורסם ב: by

“You manage your PHP project dependencies with Composer, right? But are you sure that your project is not dependent on a package with known security issues? The SensioLabs security advisories checker is a simple tool, available as a web service or as an online application, that uses the information from your composer.lock file to check for known security vulnerabilities. This checker is a frontend for the security advisories database.” / SensioLabs.

phpcs-security-audit – PHP_CodeSniffer

פורסם ב: by

phpcs-security-audit is a set of PHP_CodeSniffer rules that finds flaws or weaknesses related to security in PHP and its popular CMS or frameworks.

It currently has core PHP rules as well as Drupal 7 specific rules. Next planned CMS/framework is Symfony 2, which are also relevant to Moodle.

As a bonus set of rules, the tool also check for CVE issues and security advisories related to CMS/framework. You can use it in order to follow the versioning of components during static code analysis.

The main reasons of this project for being an extension of PHP_CodeSniffer is to have easy integration into continuous integration systems and to be able to find security bugs that are not detected with object oriented analysis (like in RIPS or PHPMD).

phpcs-security-audit is backed by Floe design + technologies and written by Jonathan Marcil.

jokkedk/webgrind: Xdebug Profiling Web Frontend in PHP

פורסם ב: by

Webgrind is a Xdebug profiling web frontend in PHP. It implements a subset of the features of kcachegrind and installs in seconds and works on all platforms. For quick’n’dirty optimizations it does the job. Here’s a screenshot showing the output from profiling:

Features

  • Super simple, cross platform installation – obviously 🙂
  • Track time spent in functions by self cost or inclusive cost. Inclusive cost is time inside function + calls to other functions.
  • See if time is spent in internal or user functions.
  • See where any function was called from and which functions it calls.
  • Generate a call graph using gprof2dot.py

Suggestions for improvements and new features are more than welcome – this is just a start.

Panda – cloud video encoding php rest api

פורסם ב: by

Getting started with Panda

At the core of Panda is a REST API which supports uploading and managing of videos, encodings and output profiles.

Every Panda account has a number of clouds. Each cloud defines a single storage for your uploaded videos, resulting encodings and thumbnails.

Typically you will want to create a separate cloud for each website you plan to integrate Panda into. You can also use clouds to separate production and staging environments.

To access the API there are client libraries available in many languages: See all client libraries. Refer to the API Docs when using the API. All API responses are JSON-formatted.

The following guides are also available: Rails How-to and PHP How-to.

API Reference.

Bitnami Blog: Performance enhacements for Apache and PHP

פורסם ב: by

Performance enhancements for Apache and PHP

In addition to updating and expanding the #Bitnami Library, we are continuously looking for ways to improve our existing Bitnami stacks. In this latest round of updates, we focused on improving the performance of our Bitnami Stacks in limited resource systems such as #Amazon #EC2 micro instances, which have 1 virtual CPU and 613 MB of RAM, and Microsoft Azure extra-small virtual machines, that ship 1 CPU core and 768 MB of RAM.

We have now configured our Virtual Machines and Cloud Images to use the #Apache Event MPM and #PHP-FPM, resulting in reduced memory usage and an increase in the number of simultaneous requests that they can handle.

 

What is the Apache event MPM?

Apache supports three different Multi-Processing Modules (MPMs) that are responsible for binding to network ports on the machine, accepting requests and dispatching children to handle the requests.
