在条件运算符中执行多个表达式

Question

How are two or more expressions executed in a conditional operator like the following which I tried but is not working in php:

$test = TRUE;
$val1 = 0;
$val2 = 0;

// want to execute two expressions where true
$test ? $val1 = 23, $val2 = 56 : "";    // this is not working

I used to do this in C++ and it worked but this is php. So how is it done in php?

Answer 1

This is not possible with PHP's Ternary Operator.

The syntax is:

 expr ? expr : expr ;

It does not allow for multiple expressions per segment. Furthermore PHP does not allow comma-separated expressions.

Regardless, your intentions will be far more clear with an if statement:

if ($test) {
  $val1 = 23;
  $val2 = 56;
}
