PHP Beginners guide

Excellent tutorial for begginers !
I just would like to add something about print and echo :
The biggest difference between them is the return value ; print can return true or false, whereas echo doesnt return anything.
However, echo is faster to execute than print. But it's only in theory, in practice, there is no difference

Thanks for this tut!

Hey man Thanks! I forgot about the return.
And there is also in practice a time difference but even over 2000 prints it's not noticeable.
I've added your post to the first post. Thanks again.

You're welcome !
You're right, i havn't ever noticed the speed difference between both, but this is the theory... maybe just a legend
As we are talking about improvements about this tutorial, you should maybe develop explicitly about $_SESSION variable, even if it's not in "begginner" leve... Maybe not explain all about this, but make more descriptive about that... Just a suggestion ^^
Keep up the good work

No, the function you mean is print_r() used to output all members of an array.

No, the function you mean is print_r() used to output all members of an array.

i mean you had a typing error.....

<?php

// declare global variable
$i = 5;

funtion print_i() {
global $i;

print $i;
}

?>

funtion print_i() ?? shouldn't it be function print_i() ?? because i tried it in my phpdesigner and an error appeared

[Spl3en]

Yeah, it's not funtion, it's function of course
Thanks for report it, NinjaGeek will surelly correct it ^^
