The document discusses PHP security best practices. It emphasizes two golden rules: 1) filter all external input and 2) escape all output. It provides examples of filtering user-submitted data and escaping it before displaying to browsers or inserting into databases. It also covers common attacks like SQL injection, session hijacking, and cross-site scripting, explaining how to prevent them by following the two golden rules of filtering input and escaping output.
See all the steps involved to build a fully functional data mapper with object-oriented PHP5 using the power and simplicity of the Standard PHP Library. Based on the early development of a new PHP DataMapper project Vance Lucas started a few months ago as the Model layer for an MVC framework.

Johannes Schlüter's PHPNW08 slides:
The current PHP version, PHP 5.3 introduced a multitude of new language features, most notably namespaces and late static binding, new extensions such as phar, as well as numerous other improvements. Even so, this power-packed release boasts better performance than older PHP releases. This talk will give you a good overview about PHP 5.3 and show some less known features in detail.
Correctly understanding the eight data types in PHP is essential to a solid foundation in development. Come refresh your knowledge of the scalar types, compound types, and special data types used in PHP, and learn about proper usage of each. Review type juggling, learn some common data type traps to avoid, and how to code defensively to prevent having the data type of a variable change unexpectedly. Finally learn how unit tests can help verify that code is handling data types correctly.
Using php as a server-side scripting language, I have created a simple user authentication module. The module can be directly implemented in a website with some minor changes to provide user signup ability in a webpage. HTML and CSS have been used for the designing of the webpage, and MySQL for backend database management.
Make an object be searchable is difficult? Taking control of search result's ranking is even more challenging.
In BarCamp Bangkhen 2015 (Nov 22, 2015), Suparit Krityakien, Co-founder & Software Architecture of Wongnai (http://www.wongnai.com) shared his experiences on applying Wongnai ranking algorithm to take control of our search engine's scoring systematically as well as what can be tuned to make it smarter.
This presentation is to furnish you with fundamental knowledge required when tweaking ranking on your search.

6. Filter example $clean = array (); if ( ctype_alnum ($_POST[ 'username' ])) { $clean[ 'username' ] = $_POST[ 'username' ]; } $clean = array (); Initialise an array to store filtered data.
7. Filter example $clean = array (); if ( ctype_alnum ($_POST[ 'username' ])) { $clean[ 'username' ] = $_POST[ 'username' ]; } if ( ctype_alnum ($_POST[ 'username' ])) Inspect username to make sure that it is alphanumeric.
8. Filter example $clean = array (); if ( ctype_alnum ($_POST[ 'username' ])) { $clean[ 'username' ] = $_POST[ 'username' ]; } $clean[ 'username' ] = $_POST[ 'username' ]; If it is, store it in the array.
