What language are u interested in and how deep have you gone already?

Hi! I am new here, I Hope I met with you in very exciting and funny mood

pls. I have a question. The question is:suppose I wrote my program completely, but eventually when I came to test it. It said unable, or there is problem across! what should l do?? do l erase completely to start new program or should l come back to check, although it seems difficult to re_check and solve, since there are ernomours characters.... l need huge explanation 4 better understanding... long life nairaland..wishing u all the bests in ur endevoars...!!! l hope to get conviencivable answers

why does this code keep telling me "invalid phone number" please help

if(!$phone){
$error[]="Invalid phone number";
} elseif (!validate_phone($phone)){
$error[]="Invalid phone number";
} elseif(phone_exists($phone)){
$error[]="Phone number already exists";
}

I don't know why people keep asking "I want to learn a programming language which one should I learn". What do you want to do:
1. Game development- you need to learn c++, c# and game engine such as unity3d
2. Desktop app- java, c, c++, c# and python. These are the best
3. Web development- Frontend: HTML, CSS, JavaScript, bootstrap. Back end: node.js, Python or java
4. Mobile development- just go for java.
So choose what you want to do out of these 4 and sign up for coursera.org or edx.org. I hope this helps.

According to the PHP manual (I assume this is PHP), things that will evaluate as FALSE in conditions are (in no particular order):

1. The number 0 and 0.0.
2. Empty strings and empty arrays.
3. The string "0".
4. NULL and unset variables.
5. SimpleXML objects created from empty tags.

So, provided that, in your script, $phone carries any of the above values, then your first IF condition would evaluate as TRUE. This is because options 1 ... 5 convert to FALSE, and !FALSE == TRUE.

The same goes for the function in the first ELSEIF statement. That ELSEIF statement will always evaluate to TRUE, provided that function returns any of the values in 1 ... 5.

So, you have to ask yourself what value exactly is your $phone variable actually carrying, and what value is the validate_phone function actually returning.

wow

If you stay in Benin City, let's chat...otherwise it's possible to learn on your own and ask someone who's more experienced anytime you have questions...all you really need is dedication...

Very good point indeed...I think you should start debugging from th point you declared your $phone variable....little typos in code can sometimes be quite hard to locate..or you can upload the full code here let's see...good luck coding!

Javanian:


Data Structures and Algorithms are a branch of computer science different from programming languages. So yes, They are courses you should spend time learning when you have gained some mastery of whatever language you are learning. But for now, you should first of all learn your language properly by working on some personal projects. When you have done that I can recommend books for you.

How can you even build a small project without understanding data structures

You need to research on carrying out unit tests, it helps prevent/reduce unsuspected bugs at the final stage of deployment.
