echo expression ? $foo : $bar;
回声表达 ? $foo : $bar;
回答by A.M.N.Bandara
The ternary operatorevaluates 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 echoone value or the other, just pass the ternary expression to the echostatement.
的三元运算符的计算结果为第二个表达式,如果第一个计算结果为的值TRUE,并计算结果为第三个表达式如果第一计算结果为FALSE。对于echo一个或另一个值,只需将三元表达式传递给echo语句。
echo expression ? $foo : $bar;
