Like the title?

Question: How come some conditional statements are formatted like this?

if (!empty($blah)){
   echo "bleh meh";
}

PHP:

And some like this?

if (!empty($blah))
   echo "bleh meh";

PHP:

Thanks,

because if u have more than 1 thing to do :

ex :

if (!empty($blah)) {

echo "bleh meh";
echo "bleh meh2";
echo "bleh meh3";
echo "bleh meh4";
echo "bleh meh5";
echo "bleh meh6";

}

You should use brackets , if its only 1 call , you can put it as the second ..

 

Just as commandos has already said.

In my personal opinion it's better practice to just use {} all the time but opinion may vary on this one...

 

If nothing else it makes it easier to understand what is where

if (A=="1")
{
echo "A = 1";
}
elseif (B=="1")
{
echo "B = 1";
}
else
{
echo "C = 1";
}

 

It's probably better practice to use brackets all the time. If you do this:

if ($foo == $bar)
  baz(); 

PHP:

You may add a statement like this:

if ($foo == $bar)
  baz(); 
  bom();

PHP:

without realizing that it will not do what you intended. An alternative is to use

if ($foo == $bar) baz()

PHP:

to avoid that confusion. But whether this really matters varies from programmer to programmer.

 

I figured it was something simple like that. Thanks for the responses!
