note 80123 added to language.operators.comparison

Try out the following, to show inconsistencies between nested ternary comparisons:

<?
function bogsdollocks($num) {
	echo "Number input = ".$num."<br>";
	//What's up with the following - 
	echo ($num == 7) ? "exactly seven" : ($num > 7) ? "more than seven" : "less than seven"  ;
	echo "<br>";
	// after much monkeying around the following is ok, note the brackets around the latter nested ternary statement - 
	echo ($num == 7) ? "TERNARY OK : exactly seven" : (($num > 7) ? "TERNARY OK : more than seven" : "TERNARY OK : less than seven" );
	echo "<br>";
	// The following is the reference which is always ok - 
	if     ($num == 7) { echo "REFERENCE : exactly seven";  } 
	elseif ($num >  7) { echo "REFERENCE : more than seven";} 
	else               { echo "REFERENCE : less than seven";} 
	echo "<br>";
}
echo "<HR>";
bogsdollocks(6); 
echo "<HR>";
bogsdollocks(7); 
echo "<HR>";
bogsdollocks(8); 
echo "<HR>";
?>

Gives the results:
Number input = 6
less than seven
TERNARY OK : less than seven
REFERENCE : less than seven
---------------------------------
Number input = 7
more than seven
TERNARY OK : exactly seven
REFERENCE : exactly seven
---------------------------------
Number input = 8
more than seven
TERNARY OK : more than seven
REFERENCE : more than seven

I try to avoid ternary.
