The ternary operator is a convenient way to conditionally return an expression. They can even be used in the middle of a string concatenation, if you use parentheses. 

Example:

if ( $wakka ) {
 $string = 'foo' ;
} else {
 $string = 'bar' ;
}

The above can be expressed like the following:

$string = $wakka ? 'foo' : 'bar' ;

If $wakka is true, $string is assigned 'foo', and if it's false, $string is assigned 'bar'.

To do the same in a concatenation, try:

$string = $otherString . ( $wakka ? 'foo' : 'bar' ) ; --was-- The ternary conditional operator is a useful way of avoiding http://phpsourcecode.blogspot.com inconvenient if statements.
