PHP functions are groups of named code which we can call from anywhere within the program. In this video we cover basic syntax for creating PHP functions as well as some advanced techniques like passing arguments by reference and using recursive functions. We also go over data type declarations, default argument values and variable scope. Learning the techniques from this video will give you a good understanding of PHP functions. ````````````````````````````````````````````````````````````````````````````````````````````` Hey guys, I'm now using Patreon to share improved and updated video lesson material.

Can I have a function in php which would take an argument and return a value? Just like in java (for example if I type "$a=function(arg1, arg2);" variable "a" would be assigned with a value the function returned. Or it's not possible? If no, how can I approach this problem if I need to store and later manipulate the value which is calculated by calling a function? EDIT: nevermind, I figured, that a simple "return $var" at the end of the code does it.

Wikipedia: The term parameter (sometimes called formal parameter) is often used to refer to the variable as found in the function definition, while argument (sometimes called actual parameter) refers to the actual input supplied at function call. Kindly correct your slides.You interchanged their meanings.

that software's so handy, can tell me where can i download that or its a website serever?
MyYou (1 year ago)
and why do you write const without the define function?
MyYou (1 year ago)
the parameters should be in the function definition and the arguments in the call

Which text editor are you using? There is an area on the right side that looks like a browser. I don't get it. Is it the part of a browser or has the editor the server simulation?
Zobair Siddique (1 year ago)
Arguments are Params, and prams are args in your video, correct me if i m wrong.
Kishan Kumar (1 year ago)
A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method's parameters.

Isn't this OO PHP? I have been told on more than one occasion, that I shouldn't learn OO PHP before learning Procedural?
Vader (1 year ago)
a better exemple of oop programming is the humans.We have many features like eyes color, hair color, the height and the weight.Once you define all of these features you can do how many humans you want with diffrent features.This paradigm of programming helps you to save memory beacause you don`t have to define the features for each human in part...but you must how to know to implement the feature at least for one...that`s why is the procedural programming first and after oop programing,I hope one of these exemples make it clear

Hello Kevin...to have a better understaning about programming i propuse to learn first procedural programming and let me explain why, when you have to solve a problem first you have start to thinking about how to solve the problem in any programming language and after to implement the solution...if two problems have the same solution you can start thinking about OOP programming because you have there the same pice of code more than once.In other ideas if you know how to solve any problem in procedural way you can use that solution has many time you want...if you know oop programming without procedural you can`t solve the problem even you know the way to reuse the code...i hope I make it clear now...if you don`t let me know
