using iif statements

can someone explain to me how to use these? can they used to check if a value is false or true and if true display something?

Syntax:

PHP Code:


		
			
if (condition is met)

{

do this

}

// Below is optional.

else if(another condition is met)

{

do this

}

else

{

do this

}

Conditions are boolean expressions, evaluated under true or false.

For example:

Code:

if ($bbuserinfo['username'] == 'some_dude')

{

echo "Hey some_dude!";

}

Check out www.php.net for more information.

PHP Code:


		
			
$variable = iif($expression, $truevalue, $falsevalue);

PHP Code:


		
			
$i = 1;

echo iif($i == 1, "i is one", "i is not one");

It is exactly the same as the built-in PHP ternary operator, and exactly the same in C, C++, and Java:

PHP Code:


		
			
$i = 1;

echo ($i == 1 ? "i is one" : "i is not one");

so you have a true and false value after $blah==whatever?

The format of this phrase

PHP Code:


		
			
if ($this == "1") {

$do = $this;

}

else 

{

$do = $that;

}

is functionally identical to the following in regular PHP

PHP Code:


		
			
$do = ($this == "1") ? $this : $that ;

PHP Code:


		
			
$do = iif($this == "1",$this,$that);
