I want to evaluate a simple ternary operator inside of a string and can't seem to find the correct syntax.
My code looks like this:
foreach ($this->team_bumpbox as $index=>$member)
echo ".... class='{((1) ? abc : def)}'>....";
but I can't seem to get it to work properly. Any ideas on how to implement this?

The term "ternary operator" refers to an operator that operates on three operands. An operand is a concept that refers to the parts of an expression that it needs. The ternary operator in PHP is the only one that needs three operands: a condition, a true result, and a false result.
ternary operator: The ternary operator (?:) is a conditional operator used to perform a simple comparison or check on a condition having simple statements. It decreases the length of the code performing conditional operations. The order of operation of this operator is from left to right.
The right answer is: it depends. Most of the time, they are about the same speed and you don't need to care. But if $context['test'] contains a large amount of data, snippet 2 is much faster than snippet 1.
The shorthand ternary operator In this syntax, PHP evaluates $initial in the boolean context. If $initial is true, PHP assigns the value of the $initial to the $result variable. Otherwise, it assigns the $default to the $result variable.
You can't do it inside the string, per se. You need to dot-concatenate. Something like this:
echo ".... class='" . (1 ? "abc" : "def") . "'>....";
Well, you can do it actually:
$if = function($test, $true, $false)
{
return $test ? $true : $false;
};
echo "class='{$if(true, 'abc', 'def')}'";
I'll let you decide whether it is pure elegance or pure madness. However note that unlike the real conditional operator, both arguments to the function are always evaluated.
