Umm what does this mean

[desithugg]

Okay well I've seen something like the following done many times in php,perl, javascript and more. But I still don't know what it really means. Can anyone tell me exactly what the statement means and how i can use it maybe.

$real_result = $boolean_result ? 1 : 0;

Ternary operator. It's a shorthand for an IF-THEN-ELSE.

 

condition ? true_expression : false_expression

 

If the condition is true, evaluate the true_expression, otherwise evaluate the false_expression.

 

In your example:

 

$real_result = $boolean_result ? 1 : 0;

 

is equivalent to:

 

if ($boolean_result)
{
   $real_result = 1;
}else{
   $real_result = 0;
}
