While loops are very popular and useful.

Of course, while loops are better if you don’t know how many iterations you have to do (eg. SQL data fetch).

There’s one detail: in C there are $i++ and ++$i constructions. The second is faster, strange. ;)

Thanks for that clarification! I actually didn’t mean it would work, I meant that it is equivalent, although I agree, I wasn’t too clear, I should have written out the proper form! I did not know it was faster though, thanks for that awesome, awesome benchmark link :)

Hi What is PHP!

Yes, from the article: “there are many tips and tricks you can use, and other modes of looping, we will get there soon though”

In some cases you must (or at least it is much easier) to use while loops, if you want some rules for a specific interval in the loop. I also use foreach a lot, I will get there in due time :)

I could also have written “$i + 1″.

Nope, because $i+1 doesn’t affect on parsed variable what $i++ does. Although the proper code should be $i = $i+1 it brings back a bad Pascal’s behaviour. PHP is C based language so use C operators which are often faster than other constructions.

Take a look: http://www.php.lt/benchmark/phpbench.php

A PHP performance benchmark which tests all possible array iterating methods.

Thanks for the explanation! Also, I agree, php.net is the best. I also refer to it a lot, I don’t have all those hundreds of built in functions in my head :)

I too have the same exact keyword in firefox :) Although I know a lot of function names I don’t always know their arguments and in which order I should put them, so this is a great quick reference!

Hi iampriteshdesai!

Sorry, but I only cover web specific topics like HTML, CSS, PHP, MySQL, Javascript, AJAX, etc. I am not that well versed in C++, while I might be able to write the program I am not sure I could do it with best practices.

However I will have time in February, and I am scheduling some learning time for C++ anyway, if this is still an issue for you pelase email me at daniel [at symbol] hackyourday [.dot.symbol] com

Thanks for helping!

echo “Hello, World”;

when you load the page it will print out Hello, World to your browser.

Because of this, you can actually place HTML/Javascript/CSS tags (anything that you would use when developing a website actually) into echo tags.

http://ca.php.net/manual/en/function.echo.php

Since the PHP manual is so great (I find myself referring to it quite a bit) I actually set up a keyword search for it. So now, I can just type in php my_search_term and it automatically searches the website. I suggest any developers do that same, as it saves a lot of time when you’re typing not to have to switch with a mouse.

In C language, I could insert a row with “printf” and then you should got a message on the screen. But php I don’t know and even so PHP commands will interact with HTML.

Thanks,

Fabius

Thanks for those links, also W3Schools is a great palce for MANY languages, check out the site at

I also like Your HTML Source at

PHP actually has one of the best online manuals ever, take a look at php.net. It can be a bit daunting at first, but it’s actually written very well.

I’ve been telling myself for years that I would someday go back to programming by learning some modern languages. Now seems like I will finally begin to tackle this project.

Here’s some links I am looking at that might be useful for others:

vb
for i as Integer = 0 to 99
msgbox “hello world”
next i

php
for($i=0; $i=99; $i++){
echo ‘why post about this, let them learn the hard way :)’;
}

vb
for i as string = 0 to 99
msgbox “hello world”
next i

c#

for (int i = 1; i <= 10; i++)
{
MessageBox.Show(”Hello World”);
}
