PHP Tutorial 18 - Functions (PHP For Beginners)

PHP already holds hundreds of built-in functions that you use in your everyday applications, but in PHP you have the ability to create your own functions. A function will carry out a pre-determined set of code and can be called whenever you want it to. Functions can also take parameters so you can specify the data that is entered into a function each time you call it. Functions can also be used to return values. This video will cover the wonderful world of functions.

Chris thank you man. I have been trying to learn PHP from 2008. Could not. One day with your videos and I got a strong foundation in PHP. Above all you have kept it free. A person like me with less money and the desire to learn knows the value of it. Thanks buddy. God bless you.

Thanks a million times, the explanations are very very clear.

Great work.Thanks for the tutorial.

Minor note: don't say "That's it" like the lesson is finished when you still have things to say. Say, "To recap, ..." Only saying this because your teaching is already so good.

good job man...i really learn something from your tut...

[hotel-california]

it's because the function is a block statement, which means instead of being like a sentence ending with a period (or semicolon), it's more like a paragraph, where it is defined by the brackets. I hope this helps :D

[Farooq]

These tutorials are very useful and i want some more complex tutorials...

i need help, i hope you are able to assist, i accidentally removed apart of the footer info in the function area and now lost my site after the update function got clicked, is there any way i can get my site back up again ? i have a copy of the stuff that was in the functions file, i copy and paste into notepad before the mistake happened, is there any way to get the web site back up and restore the function file back to normal and web site back up again ? your help would be very appreciative as its now worrying me as i no longer got access to my site

[MrJonathanRB]

[swetashanu]

sir please can you upload more vidio of php and web development and urs language is very clear and urs way of concept is very easy and undertable for beigners so really i love this tutorials

[mr_eko_]

Great videos man, thanks! Just a quick info;

The welcome() function already echo's the welcome message. Therefore, when calling the welcome() function, you don't need to echo it a second time. Just tyipng welcome(); would be enough.

Keep up the good work!

[Khasubas]

I am confuse what is the difference between return and without return in the function ? and why they are important?

[hwbacsi]

the function returns with that, so if it's a variable, like $age and then you echo the function, it will write the value of $age

Have you checked if you have any other software using port 80 on your pc/mac?
