Just clarification

I know in C++ when you do a loop or if statement or something the brackes {} are not necessary if you only need to execute one statement inside the block that is looping or being IFed.

Is this true with PHP? I know this is a dumb question, but I just want to make sure.

Examples:

if( $iamsmart == "true")
{
conquertheworld();
}

for( $i = 0; $i < 10; $i++)
{
print " $i \n ";
}

is the same as

if( $iamsmart == "true")
conquertheworld();


for( $i = 0; $i < 10; $i++)
print " $i \n ";

You need the {}.

Bah! I always thought i was cool when you could like nest stuff w/o the brackets.

One more question related to the functionality of this forum, when your typing in the "reply" box, how can you tab over w/o going to the next field in the form.

here is an example when they're not needed, i used this to make a printer friendly page..

if($_GET[action] == "print") 
{
   $header = null;
   $footer = null;
}

if ($header) include($header);


// rest if the page....


if ($footer) include($footer);

Cool. Thanks for the help!

Althought I still don't know how to tab over in the box I'm typing in right now. ( the reply <textarea> box )

I end up copying a tab from somewhere else.

And it's not good coding practice to not use { }.

People seem to use C notation. I prefer 'PHP' notation:

if (isset($elvis)) {
  echo "Blue suede shoes.<br>\n";
}
