This doesnt really relate to anything Im just curious.

Why does php still use ';'? It seems slightly archaic. Is it really necessary? Does it work faster having that at the end of each line as opposed to the server having to figure out when the line is up? Or is it more to keep in line with C and the ways people are use to programming.

Again, not complaining, just curious.

I think it's just one of those things where the language started with using line-ending semi-colons since it was originally inspired by C and Perl. At this point it would be too dramatic of a change to remove.

I think it is required if you want to allow a single statement to span multiple lines, otherwise we would have ambiguous cases just like javascript.

I don't see why it bothers you?

PHP as this syntax, others too.
Python doesn't, and use indentation to separate blocks, rather than { and }
plsql require the ; at the end, and to declare every variables, their types and their capacity before you use them, like c.

Different languages, different constraints.
Personally, I like the way PHP put constraints. Enough to not have something too messy, but not too much to still being easy.

In my memory, perl and visual basic are the most messy codes to read.

I think frost has it about right. Personally I think I would get confused if it was done by lines.

i agree, PHP is my only real programming languagae,i have a little experience of VB and it does look confusing sometimes

it all comes down to coding styles, and how the authorer prefers to read and write code,

i absolutly HATE it when people use indentations.

and for if/else statments and things hate it when i see:

PHP Code:

if(Condition) 
{ echo 'TEXZT' }
else { echo 'text' } 


i find it so messy and annouying!

i much prefer it when its spread out a little:

PHP Code:

if(condition)
{
echo "text";
}
else 
{
echo "vfd";
} 


and the ; are helpful for finding when functions and "actions" etc end.

anyway i like em i just wish php could easily be used to make desktop apps!

Dan

I like the semicolon as a statement terminator.

I will disagree with Dan, I can't stand it when people don't indent their code. With indentation, it is so much easier to find where blocks and sections begin and end.

it depends, it just annouying me when i see it when you have like


CODE
CODE
Code

when its huge and you have to scrol veritcally i have nothing gainst small or reaosnable indentations in code, its just when its uge and messy i hate it

I also disagree with Dan. This

PHP Code:

if(condition) {
    if(condition) {
        if(condition) {
            some code here...
        } else {
            something else
        }
    }
} else {
    if(condition) {
        some code here...
    }
} 


is much easier to read than this

PHP Code:

if(condition)
{
if(condition)
{
if(condition)
{
some code here...
}
else
{
something else
}
}
}
else
{
if(condition)
{
some code here...
}
} 


And semi colons are great!

I use 4 spaces of indentation. I can't stand to look at code with at least 8 and one section ends up starting on the right side of the screen. Too much indentation is unreadable and can be just as bad as none.

^ Thats what i ment...

btw i didnt mean the code thing to be like that the middle one was suposed to have a ton of spaces

@lizciz
i sort of agree but i think i would still prefer it all right align but with line breaks between each statment,

its just my pref i find your first example messy.

Also i tend to add comments to tell myslef (and others) what the curly brackets are closing if i have a few.

so i would have // END for IF CONDITION jsut makes it easier to line up and when i have too many or not enought closing brackets to track down the offending one!


WOOT GO COMMENTS!! scripts dont have enough of them!

Dan

Also i tend to add comments to tell myslef (and others) what the curly brackets are closing if i have a few.

I agree for that.
Especially when you have several if or case stuffed inside loops, in that case, both the indentation and the end-curl brace comments are useful.

And as for the indentation part, I keep it on 2 spaces (real spaces, not tabs).
I found that 4 are usually too much. You end up needing a 22" wide screen to display everything without line breaks...

^ DITTO!

Lol

Thru some programming courses etc. in school (not php actually, but I figured it should be the same) I've learned that lines should be 70-80 letters wide, for a good readability. So you don't really need a big screen, just keep the lines short. Make use of the semi colon :P

I also agree about commenting your own code, where itis nessesarry. That is, where it can make understanding the code easier.
And I use 4 spaces for indention btw.

Commenting is useful as it reminds you of what your doing (Useful if you code while drunk/tried/high like me) the next day. I'm more of a functions based person mind (like if something is used more than once, make it a function).

I never really care about line length, Dreamweaver automatically makes the code fit my screen (and tells me where the line ends).

Laying out code nicely is really useful (*Rogem tells you coding nightmare storys*). Though if I'm selling the code to someone I do not trust I may make the code nasty to read, with no comments...But not generally.

Hehe. Here is my name in perl

''=~('(?{'.('-[@@^]'^'])).*}').'"'.('*]-__}'^'`<@:,_').',$/})')

I love unreadable code
