APM (Alternative PHP Monitor) is a monitoring extension enabling native Application Performance Management (APM) for PHP. It doesn’t require any modification to your application’s code and let’s you collect performance metrics as well as catching issues that may arise.
“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 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).

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:
- 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.
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.
Powerful PHP Source Code Editor
The #NetBeans #PHP editor provides code templates and code generation tools, such as “getter and setter” generation, refactoring, such as “instant rename”, parameter tooltips, hints, and quick fixes, and smart code completion.
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.
Moodle is a web application used in educational settings. While this chapter will try to give an overview of all aspects of how Moodle works, it focuses on those areas where Moodle’s design is particularly interesting:The way the application is divided into plugins;The permission system, which controls which users can perform which actions in different parts of the system;The way output is generated, so that different themes skins can be used to give different appearances, and so that the interface can be localised.The database abstraction layer.
At Google IO this year, Google announced support for a new runtime running on App Engine, PHP. Currently, they have full support for languages such as Python, Java, and Go. PHP on App Engine was the number one request voted by developers and Google has finally delivered. PHP empowers a great percentage of the web sites in the world, it is very likely this will be taken out of Experimental mode soon into full Production mode. Google has taken the open source PHP 5.4 platform and augmented it to run on App Engine. They created a safe “sandboxed” environment for your apps.
