if()

[vTurato]

You only use braces if it's more than one line in an if statement

Sorry, but i didn't get you.....
Do you want any help regarding "if" statements.???

vTurato, that's not totally true. the syntax is:

if([I]condition[/I])
{
[I]action[/I]
}

 

[diabolo]

just to clarify if() has two possible syntax

if the action clause is in a single line:

if(argument) action;

or

if(argument) {action;}

or if it spans over multiple lines:

if(argument){
  action1;
  action2;
}

 

[xPlozion]

ichwar, he is actually correct. If you've only got one line after the if statement, you don't need braces.

if ($value == true)
  echo "Hi";
else
  echo "Bye";

 

[freecrm]

Just to add to diablo's points (which are correct)..

"One line" should read "one command", followed by a semi colon;

i.e. echo "something";

This can be done either on the same program line or with a return.

syntax readability wise, it's better to use one line for everything when there is one command

if(argument) action;

and braces when there is many commands

if(argument){
  action1;
  action2;
}

I disagree.
I think it is better to put the execution statement on a separated line to the condition statement. Indented, of course. That way, it becomes far more clearer to distinguish the condition and statement, and to match them up.

But of course, everyone works in a different way, and when it comes down to a difference in [parser ignored] whitespace, the final effect will be no different.

 

[xav0989]

Not to contradict you, but when you work on projects with dozen of 1000 lines pages, you prefer the one line statements, although to indent everything might seem nicer.

 

[xPlozion]

Stop arguing, because it's an opinion. My preference is the same as Schoochi, but it's just a preference.

I've got some scripts that are over 1000 lines and i think it's easier to distinguish conditionals, because it's a new tab and not the same line.

if ($act == "main")
{
    echo "hi";
    if ($logged) echo "welcome";
    $a*5;
}

vs

if ($act == "main")
{
    echo "hi";
    if ($logged)
        echo "welcome";

    $a*5;
}

Can you have multiple arguments using ANDs and ORs with php?

 

[xav0989]

yes, AND is && and OR is ||

@xPlozion:
Was about to right pretty much the same thing...

Thanks xav, that tidies my code up
