Ternary Operator and the IIF function

The standard PHP If statement can be reduced by the ternary operator, which is described in the PHP manual Comparison Operators. The IIF function puts the ternary operator into a function.

Ternary Operator

conditional ? if_true : if_not_true;

is the same as

if (conditional)
  {
  if_true
  }
  else
    {
    if_not_true
    }

IIF Function

To return the result of the ternary operator

function iif($expression, $returntrue, $returnfalse = '') {
    return ($expression ? $returntrue : $returnfalse);
}
