我想为多个变量If条件简写添加值

Question

I want to add value to multiple variable If condition shorthand but I don't know how to use symbol split between 2 variable

eg. manuscript

if(condition) {
    $var1 = "a";
    $var2 = "b";
} else {
    $var1 = "";
    $var2 = "";
}

Shorthand [error]

(condition) ? $var1 = "a", $var2 = "b"
: $var1 = "", $var2 = "";

Don't do it. The if statement is fine. It's simple and clear. Try to cram multiple assignments into the ?: ternary operator, next thing you know you're hacking Perl scripts for spare change in some back alley.

I would write exactly what you have:

if (condition) {
    $var1 = "a";
    $var2 = "b";
} else {
    $var1 = "";
    $var2 = "";
}

You could potentially write it like this, if you prefer. This is a good choice if you first assign default values and the if condition assigns less common values.

$var1 = "";
$var2 = "";

if (condition) {
    $var1 = "a";
    $var2 = "b";
}

If you really want to use the ternary operator you could write this, if you're okay writing condition twice:

$var1 = condition ? "a" : "";
$var2 = condition ? "b" : "";
