We agreed earlier that I will not be offering PHP lessons in this blog. Forgive me for that. I will only use this language to present the whole idea of SMS and USSD. However, I will discuss a few things that are necessary to easily understand the subject in question.
I am of the assumption that you are aware of he following
- PHP escape tags (<?php........?>)
- That PHP files has extension .php
- Declaring variables in PHP(use of $ sign)
- That PHP is untyped language
- The "echo" command
- Arithmetic operations and string concatenation
- Using functions in PHP (User defined and inbuilt, and those with parameters and those without, and passing and receiving arguments in parametrized functions)
- Control structures with a special emphasis on switch....case...
- The POST[] and GET[] global arrays or methods
- Receiving variable values through a URL
- Including PHP files in others
- Arrays
Why PHP language ?
- It is easier to learn. This means that USSD learner will understand the USSD concept easily
- Widely supported
- Many developers are using it, which means it is easier to get assistance
- It is interpreted rather that complied, and thus saves time, especially for learners where a lot of testing is necessary
Because some PHP parts above will be highly used in this tutorial, the following sections will be discussed prior to handling USSD concepts;
- The switch...case control structure
- Arrays
- Functions (inbuilt and user defined)
- Receiving variable values from a URL
This means that if you are green about PHP, you should not worried. However, take you time and acquaint yourself with basics.
This was not really a post or lesson, but it is equally important.
Ask me a question and I will be glad to respond. You can also subscribe to be notified when i have posted a lesson.
