PHP if shorthand and echo in one line - possible?

问题

What's the best, preferred way of writing if shorthand one-liner such as:

expression ? $foo : $bar

Plot twist: I need to echo $foo or echo $bar. Any crazy tricks? :)

回答1:

<?=(expression) ? $foo : $bar?>

edit: here's a good read for you on the topic

edit: more to read

回答2:

echo expression ? $foo : $bar;

回答3:

The ternary operator evaluates to the value of the second expression if the first one evaluates to TRUE, and evaluates to the third expression if the first evaluates to FALSE. To echo one value or the other, just pass the ternary expression to the echo statement.

echo expression ? $foo : $bar;

Read more about the ternary operator in the PHP manual for more details: http://php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary
