Aspect-oriented programming (AOP) is a programming paradigm that allow to increase modularity by provide better options regarding the separation of cross-cutting concerns.
PHP currently hasn't native support for AOP, but from PHP v5.4 are at least are few solutions provided by community that can support AOP usage in PHP.
Concrete5 is a relative new CMS on the market, written in PHP and even if first beginnings are somewhere in 2003, only from 2012 was started to be updated with regularity
From the beginning was design to be very user friendly CMS, to require small level of knowledge in order to be able to use it
Coding standards are very important in any programming language. Until now was developed all kinds of coding standard conventions by major php application communities like Zend, Symfony, Drupal and so on. But PHP as language had no any type of standard regarding coding style.
I had to made a few days ago, a php countdown timer, which runs from the command line, for educational purposes.
Script receive as input a number of seconds that converts then in days, hours, minutes, seconds, and display time. If receive another parameter t after display time it starts to countdown.
URL(s) can only be sent over the Internet using the ASCII character-set. Often especial when we generate when automatically generating url(s) we need to make sure that contains only ASCII character-set
To ensure that our url(s) contain all the time only allowed characters we can encode url(s). For this PHP has few handy functions (like urlencode, rawurlencode) that make all work for us.
The simplest way to get ip address of is to use server variable $_SERVER['REMOTE_ADDR']. Ip address of user can be used for logging, statistics, geo-targeting or ban systems.
Anyway sometimes $_SERVER['REMOTE_ADDR']. is not real IP address, when user for example using a proxy. So for more accurate detection of user IP address we need a little bit more code.
In developing process, if you want to store a value that will remain the same along your script’s execution, you can define a constant.
Also PHP has some magic constants like PHP_VERSION, __LINE__, __FILE__, E_ERROR, __DIR__, __FUNCTION__, __CLASS__, and __METHOD__, E_ALL and others wixh can help you in your application development.
A data type is defined as a set of entities and the allowable operations on those values. Almost all programming languages explicitly include the notion of data type, though other languages may use different terminology.
And PHP has defined several data types.
This article contains few words about what is new and what was changed in PHP 5.4.
Here are some main features of php 5.4:
Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle: first the developer writes a failing automated test case that defines a desired improvement or new function, then produces code to pass that test and finally refactors the new code to acceptable standards.
In test-driven development a developer creates automated unit tests that define code requirements then immediately writes the code itself. The tests contain assertions that are either true or false. Passing the tests confirms correct behavior as developers evolve and refactor the code. Developers often use testing frameworks, such as xUnit, to create and automatically run sets of test cases.
What Is Security?
Security is an important aspect to take into consideration for any web application. Security must be balanced with expense, usability. Security increase the value of your application and spares you of possible future problems.
Even if nowadays most of web php application are written using various frameworks, or platforms for a beginner i consider that first of all he should learn to develop application in pure PHP code. For those who continue to develop, web application using pure PHP code i present below some usefull functions/ piece of code used in developing php application from scratch. 1. Function that connect to db.
